1 00:00:04,260 --> 00:00:11,740 The proposition is, it has to do with the acronym you heard several times today, NISQ. 2 00:00:12,840 --> 00:00:15,560 Noisy Intermediate Scale Quantum. 3 00:00:15,560 --> 00:00:19,400 You know we are in the NISQ era right now. 4 00:00:19,400 --> 00:00:33,640 And so the proposition for the village is, this village believes that the current state of NISQ is already enabling quantum advantage for those who know how to use these technologies. 5 00:00:34,240 --> 00:00:39,460 Arguing for, I'm sorry, yes, for the proposition is Rafal Janik. 6 00:00:39,460 --> 00:00:41,640 Other way around, sorry. 7 00:00:41,800 --> 00:00:44,540 Konstantinos, you're arguing for the proposition. 8 00:00:45,380 --> 00:00:48,200 Raf, you're arguing against the proposition. 9 00:00:48,520 --> 00:00:54,900 And I wanted to say this is so very important because we heard from both of them earlier today. 10 00:00:54,900 --> 00:00:57,420 You both know they know their stuff. 11 00:00:57,420 --> 00:01:00,200 And it is going to help us come to our conclusion. 12 00:01:00,300 --> 00:01:04,080 So first for the proposition, Konstantinos. 13 00:01:04,080 --> 00:01:05,720 If you like we can switch halfway. 14 00:01:05,720 --> 00:01:06,660 Yeah sure. 15 00:01:09,280 --> 00:01:20,980 So do we need fault-tolerant quantum computing to do anything useful? 16 00:01:22,100 --> 00:01:24,100 I don't think so. 17 00:01:24,280 --> 00:01:31,200 If there's one thing I've learned in this decade of quantum that I've been messing around, we get surprised all the time. 18 00:01:31,200 --> 00:01:34,860 So just real high level, first of all, we constantly are getting surprised. 19 00:01:34,860 --> 00:01:45,780 We find little performance edges here and there, little clever ways to do things like hybrid, where some of it's classical, some of it's quantum, and you put the two together and you see some kind of like performance edge. 20 00:01:46,280 --> 00:01:59,440 So I'm not gonna worry too much about like provable, benchmarkable advantage so much as like can you identify some step in a process that could be improved with quantum over classical. 21 00:01:59,440 --> 00:02:00,860 So I think we can. 22 00:02:00,860 --> 00:02:02,740 And I've already seen signs of it. 23 00:02:03,900 --> 00:02:07,380 Recently IBM did their error mitigation. 24 00:02:07,500 --> 00:02:18,120 So they were able to show that basically we were able to cancel out some noise by doing lots of runs and statistically removing it kind of accounted for it, just to keep it real simple. 25 00:02:18,360 --> 00:02:31,420 So it's error mitigation, but there's also error suppression, where you can understand how a particular machine works, and then, for example, you can go through and flip something to reverse an error before it starts to form. 26 00:02:33,640 --> 00:02:39,780 So these kinds of things could already show some benefit, and they did in the case of the IBM papers. 27 00:02:41,260 --> 00:02:48,540 So when you look at all those kinds of things, you're going to start to see some provable, I guess what I like to call a customer advantage. 28 00:02:48,540 --> 00:02:52,420 It's like when you look at everything and you apply it, you kind of get some kind of edge. 29 00:02:52,620 --> 00:03:04,220 I wrote a paper on doing portfolio optimization with cardinality constraints, and we were able to show some performance gain using D-Wave's hybrid solver and some approaches . 30 00:03:04,380 --> 00:03:06,700 So yeah, it's not a benchmarkable advantage. 31 00:03:06,700 --> 00:03:10,680 I'm not claiming that from rooftops, but we were able to show some gain to that customer. 32 00:03:10,980 --> 00:03:14,540 So I do think when you consider all those things, we're getting close. 33 00:03:14,540 --> 00:03:24,680 And one last thing I'll add, Quantinium recently, they did that whole thing with three, we'll call them logical in quotes, qubits that were able to simulate the energy states of an H2 molecule. 34 00:03:24,680 --> 00:03:26,140 So we're getting there. 35 00:03:26,140 --> 00:03:27,420 We're like, we're approaching. 36 00:03:27,420 --> 00:03:28,240 We're not going to go. 37 00:03:28,240 --> 00:03:32,100 So I think these little tweaks along the way will enable that. 38 00:03:32,220 --> 00:03:32,820 Awesome. 39 00:03:32,820 --> 00:03:33,820 Your rebuttal. 40 00:03:34,260 --> 00:03:35,860 Or your argument against it. 41 00:03:36,020 --> 00:03:40,860 I feel a little bit underprepared without memes on the screen behind me right now. 42 00:03:42,580 --> 00:03:47,940 So quantum computing has a lot of promise, and it's actually a really hard path to get there. 43 00:03:48,420 --> 00:04:01,900 Not only do I not believe that we're at the position right now where we're delivering on that promise, I'd also like to add that it's actually a distraction from the hard work that we have to do to focus on the NIS era. 44 00:04:02,080 --> 00:04:03,900 And there are a couple definitions to cover. 45 00:04:03,900 --> 00:04:05,760 The first one is quantum advantage. 46 00:04:05,920 --> 00:04:11,020 This is not being able to do something better than a classical computer. 47 00:04:11,020 --> 00:04:16,780 This is being able to do a meaningful task better than a classical computer. 48 00:04:17,200 --> 00:04:30,100 If anyone's curious, today while sitting over there preparing for this debate, I did a quick search and I found 41 instances of people claiming quantum advantage over the last 20 years. 49 00:04:30,140 --> 00:04:32,440 All of those have not come true. 50 00:04:32,440 --> 00:04:35,860 They really fall down for two reasons. 51 00:04:35,860 --> 00:04:39,960 One, they're flat-out fraudulent, which is probably the bulk of them. 52 00:04:39,960 --> 00:04:51,200 The other one comes down to the fact that classical algorithms are incredibly good and many quantum researchers are not classical algorithm researchers. 53 00:04:51,260 --> 00:05:02,920 So what you actually see, and historically we've seen this with multiple companies, is a claim of quantum advantage and two days later a proof that there's a classical method that is far better. 54 00:05:03,100 --> 00:05:06,460 Also, there's a lot of value in quantum computing today. 55 00:05:06,460 --> 00:05:08,180 I don't want to discount that. 56 00:05:08,240 --> 00:05:13,540 There's the value of what we're doing scientifically and all the research it's been able to unlock. 57 00:05:13,540 --> 00:05:20,400 There's the value around quantum adjacent technologies such as, you know, we've heard quantum inspired algorithms. 58 00:05:20,400 --> 00:05:25,460 All these are delivering value, but the one thing we have not seen is quantum advantage. 59 00:05:25,560 --> 00:05:37,340 And you would not believe how many companies, how many academic institutions, how many researchers only care about running a NISQ right now because they're able to run on hardware. 60 00:05:37,360 --> 00:05:51,720 Instead of thinking, how do we prepare for the hardware that's going to be here five years, ten years from now, moving past the NISQ era, not necessarily into fault-tolerant, but maybe to not noisy intermediate-scale quantum computers. 61 00:05:51,760 --> 00:05:59,480 Quantum computers that have gate fidelities and qubit fidelities that actually allow us to go deep enough in algorithms to show meaningful value. 62 00:05:59,800 --> 00:06:01,920 Great, we have ten minutes for rebuttals. 63 00:06:01,920 --> 00:06:03,420 So, your first rebuttal. 64 00:06:03,900 --> 00:06:10,380 Yeah, well, I mean, I don't disagree with anything you said, technically, so I don't know if I'm going to set this off on you. 65 00:06:12,120 --> 00:06:13,380 It's all good. 66 00:06:14,240 --> 00:06:22,460 I just think that we're not, you know, I wasn't bringing up any examples, obviously, of the advantage claims that were useless. 67 00:06:22,460 --> 00:06:23,220 I hate that. 68 00:06:23,220 --> 00:06:26,360 It's like, look, we did this thing that you're never going to do, but we did it better. 69 00:06:26,360 --> 00:06:27,420 It's like, okay, cool. 70 00:06:27,920 --> 00:06:30,820 It's just like, I don't like when someone writes code and then hacks it. 71 00:06:30,820 --> 00:06:32,240 That's kind of useless, too. 72 00:06:33,220 --> 00:06:36,860 You don't want to, like, write your implementation and hack it. 73 00:06:37,800 --> 00:06:46,340 So, I agree in that space. 74 00:06:46,340 --> 00:06:49,100 And that's why I got big time into quantum-inspired. 75 00:06:49,100 --> 00:06:52,600 You know, that's why attention networks, we're hoping to see some gains there. 76 00:06:52,600 --> 00:06:56,680 But I keep seeing that hybrid thing, you know, and I can't let it go. 77 00:06:56,680 --> 00:07:05,740 I just got this feeling that we're going to be able to take advantage of some of those hybrid learnings and apply them in the work stream. 78 00:07:05,740 --> 00:07:08,560 Because, like, very few problems are solved in one step, one thing. 79 00:07:08,800 --> 00:07:10,760 You know, like supply chain issues. 80 00:07:10,760 --> 00:07:13,660 There's, like, a million places where you could try and improve something. 81 00:07:14,540 --> 00:07:21,640 So, I just have a feeling in my gut that we're going to see the ability to tweak just a few of those the right way. 82 00:07:21,640 --> 00:07:24,980 And they're like, we're sort of, like, knocking on the door of that. 83 00:07:24,980 --> 00:07:27,760 And then there's also the machine technologies that are evolving so fast. 84 00:07:27,760 --> 00:07:29,800 So, I just go into it for a second. 85 00:07:30,180 --> 00:07:31,920 Like, neutral atom, for example. 86 00:07:32,180 --> 00:07:36,980 We're talking high qubit counts, really long lifetimes. 87 00:07:37,000 --> 00:07:47,480 Like, we're expecting the next generation of neutral atom machines that are coming out within a year or so to have lifetimes of, like, I don't know, tangling times of 10 seconds or so. 88 00:07:47,480 --> 00:07:53,340 10 seconds is like, you know, the age of the universe, practically, when you're thinking about a quantum computer, you know. 89 00:07:53,580 --> 00:07:57,640 So, if we have a tangle time of 10 seconds, it makes things a little more interesting. 90 00:07:58,320 --> 00:08:01,640 Right now, they're running what's called analog mode, which is, like, not quite. 91 00:08:01,640 --> 00:08:04,540 You can't run gates on them, so it's a little closer to annealing than it is to gates. 92 00:08:04,540 --> 00:08:05,880 But they will be running gates. 93 00:08:05,940 --> 00:08:12,680 And they're gonna have modes where you're gonna be able to sacrifice a few extra qubits to get, like, better fidelity when needed. 94 00:08:12,840 --> 00:08:25,560 So, whenever you think about those, like, out-of-the-box approaches, I just have a feeling we're gonna see, like, at least a few of the problems show, like, some kind of advantage relatively soon, without true, you know, fault tolerance. 95 00:08:26,340 --> 00:08:26,920 Great. 96 00:08:26,920 --> 00:08:28,120 Rob, your rebuttal. 97 00:08:28,740 --> 00:08:34,640 I mean, this might get into a weird debate because we're gonna start agreeing with each other more than disagreeing. 98 00:08:34,980 --> 00:08:38,600 But I'd like to point out a few things that were brought up a moment ago. 99 00:08:39,080 --> 00:08:41,340 Longer lifetimes, better fidelities. 100 00:08:41,340 --> 00:08:43,900 This actually pushes us out of the misc era. 101 00:08:44,240 --> 00:08:52,940 Everything that we're talking about doing, that we want to do, requires much longer lifetimes, much better fidelities. 102 00:08:52,940 --> 00:09:00,840 We know a handful of algorithms, and you can count them on one hand today, that can prove quantum advantage. 103 00:09:02,080 --> 00:09:03,760 That's a little bit worrying. 104 00:09:03,760 --> 00:09:16,720 Instead of worrying about which optimization problem can we try to jam onto a processor today, we should be worrying about how do we actually expand the number of algos that can provide quantum advantage in the future. 105 00:09:17,440 --> 00:09:24,820 Maybe even a little more scary than that is the fact that only one of those provides exponential advantage. 106 00:09:25,260 --> 00:09:32,980 And there's been papers out of Google AI in the past that demonstrate, even with fault tolerance, quadratic advantage might not be enough. 107 00:09:33,000 --> 00:09:46,000 The overheads to build a quantum computer, the way that you actually perform the error correction, might require much higher speedups than quadratic in order to actually overcome the overhead. 108 00:09:46,060 --> 00:10:00,000 So I would encourage everyone again to not worry about jamming your algo today, your H2 molecule, which you can simulate on your laptop and calculate the ground state on, without needing a quantum computer. 109 00:10:00,000 --> 00:10:15,080 But actually start focusing on understanding how do you improve the readout method for a quantum computer beyond the quantum phase estimation, which pretty much every quantum chemistry algo is based on today. 110 00:10:15,340 --> 00:10:31,020 We have a few more minutes for rebuttals, but those of you just coming in, I want you to know what we're debating is the state of current quantum computers and if the state of current quantum computers is good enough to give advantage, real strategic advantage, 111 00:10:31,020 --> 00:10:32,920 to those who really know the technology. 112 00:10:32,920 --> 00:10:36,280 We're arguing for and against and then we're in the middle of our rebuttals. 113 00:10:36,280 --> 00:10:39,400 In a few minutes we'll get to audience questions and answers and inputs. 114 00:10:39,500 --> 00:10:43,340 So we have two more minutes for final comments before we get to questions and answers. 115 00:10:43,360 --> 00:10:45,860 In keeping with the theme, I agree with everything you said. 116 00:10:47,960 --> 00:10:48,640 Guys! 117 00:10:49,060 --> 00:10:50,140 I'm sorry. 118 00:10:51,860 --> 00:10:53,400 We agree but disagree. 119 00:10:53,400 --> 00:10:53,800 Yeah . 120 00:10:54,400 --> 00:11:01,980 But like you said about not worrying about doing a thing that you can simulate on your laptop or whatever, the whole point is like the way it was done, right? 121 00:11:01,980 --> 00:11:08,100 You know, just like the first time we ran Schumer's algorithm, it wasn't that we couldn't do 15 is 5 times 3. 122 00:11:08,100 --> 00:11:09,300 I mean, you could do that. 123 00:11:09,300 --> 00:11:10,780 It's just the way it was run. 124 00:11:10,780 --> 00:11:21,340 So like the fact that we're approaching fault tolerance through these logical qubits, that we're doing things like error suppression, mitigation, like these are like the building blocks. 125 00:11:21,340 --> 00:11:23,940 So I just view them as incredibly important for that purpose. 126 00:11:23,940 --> 00:11:31,800 Even if we could still run the math on a classical machine, I feel like without those building blocks being proven, we're not going to get far enough fast enough. 127 00:11:31,800 --> 00:11:35,500 I actually like the Shor example quite a bit. 128 00:11:36,080 --> 00:11:42,500 So I think I had the meme up earlier, which was factoring 15 into its primes versus the promise of Shor's. 129 00:11:42,500 --> 00:11:51,740 When Shor's first came out, the implementation actually would never run on a physical quantum computer with any imperfections. 130 00:11:51,740 --> 00:11:53,620 You needed the idealistic machine. 131 00:11:53,920 --> 00:12:11,260 And what I would say has been much more important to the development of actually running Shor's has been the work done from the top down, bringing the overheads required for Shor's down, instead of worrying about can you demonstrate factoring 15 on a quantum computer. 132 00:12:11,260 --> 00:12:18,220 It's again a great flex, I would say, to do that and to show that, but it's not doing actual meaningful work. 133 00:12:18,500 --> 00:12:37,760 One final point that can probably prove that there is no real quantum advantage, and it's the fact that the people like myself and the folks from Oxford Quantum Circuits are not locked away in a basement right now, working for whichever government that they happen to be under the control of. 134 00:12:37,760 --> 00:12:46,780 Because that really will happen as we get closer and closer to true quantum advantage, because the regulations just haven't caught up to where the technology is headed. 135 00:12:48,480 --> 00:12:50,720 Yeah, I was just thinking they're going to steal the machines. 136 00:12:50,720 --> 00:12:52,280 I didn't want them to steal you guys too. 137 00:12:52,280 --> 00:12:54,260 I think we go with them. 138 00:12:54,260 --> 00:12:56,120 There's no separating the two. 139 00:12:56,200 --> 00:13:00,180 And to be fair, it won't be me, but those two guys are definitely in trouble. 140 00:13:01,020 --> 00:13:05,920 I know there's no true quantum advantage right now, because everyone would know about it. 141 00:13:05,920 --> 00:13:07,440 It would be big news. 142 00:13:07,440 --> 00:13:13,060 But I do believe that we're going to have actual usable use cases. 143 00:13:13,060 --> 00:13:19,360 I just think we're going to have them before we're proclaiming true fault-tolerant intense gate caps. 144 00:13:20,560 --> 00:13:22,940 And then watch out for those oddball developments. 145 00:13:23,720 --> 00:13:25,700 Every once in a while, one of them is going to come true. 146 00:13:25,700 --> 00:13:30,980 Maybe not that Chinese paper that you need 327 qubits to crack RSA. 147 00:13:30,980 --> 00:13:32,240 Maybe not that one. 148 00:13:32,400 --> 00:13:34,440 But something like that might happen too. 149 00:13:34,860 --> 00:13:36,940 That's the one thing I just want to remind you of. 150 00:13:36,940 --> 00:13:39,840 These surprises are just things we never would have thought of. 151 00:13:40,240 --> 00:13:41,320 I keep seeing things. 152 00:13:41,320 --> 00:13:42,680 I'm like, I didn't see that coming. 153 00:13:42,680 --> 00:13:43,220 Cool. 154 00:13:43,460 --> 00:13:45,960 So that's one of the greatest things about working quantum. 155 00:13:47,760 --> 00:13:48,340 Thanks. 156 00:13:48,340 --> 00:13:51,360 And now it's time to transition to your inputs before we vote. 157 00:13:51,360 --> 00:13:57,960 You get an opportunity to ask questions, make comments, push back, make your own arguments, and then we will vote on the proposition. 158 00:13:57,960 --> 00:13:58,740 I saw yours first. 159 00:13:58,740 --> 00:13:59,140 Please, sir. 160 00:13:59,700 --> 00:14:05,000 So what do you think is holding up the development of those quantum algorithms? 161 00:14:05,000 --> 00:14:09,820 Is it that we don't have the right people trying to build the quantum algorithms right now? 162 00:14:09,820 --> 00:14:15,600 Or that we're lacking hardware to play around with to validate those, the simulation capabilities? 163 00:14:16,100 --> 00:14:16,960 What are your thoughts? 164 00:14:16,960 --> 00:14:21,760 All right, just to repeat the question, it is, what do you think is holding up the development of these quantum capabilities? 165 00:14:22,380 --> 00:14:23,400 Both of you, please. 166 00:14:23,400 --> 00:14:28,380 I think broadly, I would say tooling. 167 00:14:28,600 --> 00:14:32,720 And I know it might be a very simple answer, but it actually encompasses quite a bit. 168 00:14:33,360 --> 00:14:37,600 You know, somebody mentioned it's like being in the 1940s right now, quantum technology. 169 00:14:37,680 --> 00:14:40,680 I'd say that that's generous where we are. 170 00:14:41,020 --> 00:14:44,780 We're hoping we're going to move more quickly compared to digital computing. 171 00:14:44,900 --> 00:14:51,940 But it really is like, you know, before the development of digital computing, trying to come up with potential algorithms. 172 00:14:53,300 --> 00:14:57,540 We don't have the software tooling to allow researchers to do what they need to do. 173 00:14:57,540 --> 00:15:00,840 We don't have the hardware tooling for them to be able to test it out. 174 00:15:01,680 --> 00:15:08,380 And unfortunately, we also don't have the person power in order to actually go after this very aggressively. 175 00:15:09,560 --> 00:15:15,360 You know, I'll plug a little bit of the work that the team at the company I work at did, Xanadu. 176 00:15:16,360 --> 00:15:27,860 Looking at the simulation of batteries, again, not on today's computers, but in ones that might exist in a decade or in five years from now, they reduced the gate count by a factor of 40,000. 177 00:15:28,300 --> 00:15:28,840 Right? 178 00:15:28,960 --> 00:15:31,140 And this is, I would say, low-hanging fruit. 179 00:15:31,140 --> 00:15:31,940 They might disagree. 180 00:15:31,940 --> 00:15:33,280 That was a lot of hard work. 181 00:15:34,300 --> 00:15:36,480 But these are the type of gains that we can make. 182 00:15:36,480 --> 00:15:40,560 Unfortunately, the total gate count that you need is still a ways away. 183 00:15:40,660 --> 00:15:49,520 But we should be pushing that from the top down as we push the hardware from the bottom up until they finally converge in some place where we can deliver something meaningful. 184 00:15:51,120 --> 00:15:55,000 Yeah, some of this is theoretical, right? 185 00:15:55,000 --> 00:15:59,880 If you think about it, the greatest algorithms of all time were developed without quantum gear, right? 186 00:15:59,880 --> 00:16:00,700 They just work. 187 00:16:01,020 --> 00:16:03,040 You know, you go right back to the very first one. 188 00:16:03,500 --> 00:16:05,600 Well, they're still the greatest of all time. 189 00:16:06,500 --> 00:16:09,860 So they were in 1994, 1996, we had nothing. 190 00:16:09,860 --> 00:16:11,140 You know, they were just a dream. 191 00:16:12,160 --> 00:16:16,540 So I do think at some level it's going to be ingenuity, you know? 192 00:16:16,600 --> 00:16:19,280 And it might not even be human ingenuity, right? 193 00:16:19,280 --> 00:16:24,700 Like, for all we know, we'll get sparks of AGI in a quantum vein. 194 00:16:24,700 --> 00:16:31,860 You know, you'll be like, hey, insert name of LLME love, write me a new quantum algorithm, and it might be possible. 195 00:16:32,880 --> 00:16:33,920 So there's that too. 196 00:16:33,920 --> 00:16:35,120 It might not be us. 197 00:16:35,360 --> 00:16:40,640 Or AGI might solve some of the engineering hurdles and things. 198 00:16:40,640 --> 00:16:49,740 Not to turn this into a whole LLM discussion, but just because of what I've seen with, like, working with tensor networks and compressing them, I think there's a lot more potential there that could be tapped. 199 00:16:49,740 --> 00:16:51,140 So I would like to see that. 200 00:16:51,140 --> 00:16:55,300 So I think what we're missing is also that we're just limiting it to human beings. 201 00:16:55,360 --> 00:16:57,360 And it might be, you know, one of our friends. 202 00:16:57,360 --> 00:16:59,140 Before they kill us, they might help us. 203 00:17:01,460 --> 00:17:02,060 Great. 204 00:17:02,060 --> 00:17:03,000 There's a comment here. 205 00:17:03,000 --> 00:17:03,660 Thanks. 206 00:17:04,440 --> 00:17:11,280 So in your definition of quantum advantage, you mentioned meaningful tasks. 207 00:17:12,360 --> 00:17:19,620 And you also mentioned, I heard, go around real strategic advantage and something meaningful. 208 00:17:19,680 --> 00:17:31,460 I want to know what were the benchmarks and the measurements that determine what a meaningful task is, rather than the terms kind of sounding like they are shrouded by subjects. 209 00:17:31,940 --> 00:17:35,520 Good question about what is a meaningful task in your mind. 210 00:17:36,080 --> 00:17:38,940 I can tell you what not a meaningful task is. 211 00:17:38,940 --> 00:17:50,420 And it's an achievement I'm very proud of that, again, Google demonstrated first, but we were able to achieve at Xanadu, which is something called quantum supremacy or quantum computational advantage. 212 00:17:50,420 --> 00:18:09,120 And this is cherry picking a mathematical task that a quantum computer is really good at, but classical computers are very bad at, but that you can demonstrate mathematically from first principles that you've done with a quantum computer and it would take you millions of years, 213 00:18:09,120 --> 00:18:14,920 hundreds of years, whatever it is, but much longer with all the computational power in the world to deliver. 214 00:18:14,920 --> 00:18:18,840 And this has been demonstrated now five times, I believe, maybe four times. 215 00:18:19,360 --> 00:18:23,020 Right, on an optical and a photonic and a supercomputer. 216 00:18:23,120 --> 00:18:30,160 Great engineering milestones, whether they're necessary to get to where you're going, it depends on your your roadmap. 217 00:18:30,420 --> 00:18:35,040 Now, quantum advantage, it's not a very well defined term. 218 00:18:35,040 --> 00:18:39,320 In fact, none of these terms are, they kind of exist out in the zeitgeist. 219 00:18:39,760 --> 00:18:43,040 But what I would say is, it comes down to money. 220 00:18:43,040 --> 00:18:51,680 If it's something that somebody is willing to pay you for, and somebody doesn't show up the next day and say, I could do this faster classically. 221 00:18:51,680 --> 00:18:52,660 So let me rephrase that. 222 00:18:52,660 --> 00:18:58,820 If somebody who is well informed is willing to pay you for it, then it's real quantum advantage. 223 00:18:58,960 --> 00:19:06,700 And very honestly, it's not something we've seen yet from any quantum company, unless they've achieved it and have been incredibly secret. 224 00:19:08,020 --> 00:19:09,100 Yeah. 225 00:19:09,380 --> 00:19:15,180 So with quantum advantage, right, you're just, it has to be useful. 226 00:19:15,200 --> 00:19:17,400 It's moving the goal post argument. 227 00:19:17,400 --> 00:19:21,940 So some scientists don't like it because they're like, no, no, no, if quantum could do better than classical, that's advantage. 228 00:19:22,060 --> 00:19:24,340 But again, it's a useless problem. 229 00:19:24,340 --> 00:19:30,140 Are you just inventing some, you know, a hamster running in a wheel for no purpose, and quantum can run faster? 230 00:19:30,140 --> 00:19:31,520 It's kind of useless, right? 231 00:19:31,680 --> 00:19:34,840 So that's sort of what we've had so far, unfortunately. 232 00:19:35,300 --> 00:19:40,140 To get some of the advantage like I'm talking about, we've had to do other things too. 233 00:19:40,140 --> 00:19:47,060 Like I talked about tensor networks before, like, you know, we've used those to compress neural networks and then layer them in and et cetera. 234 00:19:47,060 --> 00:19:51,960 Like you get some other little bits of advantage along the way, and then you get your performance increases. 235 00:19:51,960 --> 00:19:54,080 But yeah, I can't claim we have quantum advantage. 236 00:19:54,360 --> 00:20:11,340 One thing to be careful of when you see these claims, often people will say this can't be simulated as a claim to prove the power of the quantum computer. 237 00:20:11,380 --> 00:20:14,980 But we can't simulate on a quantum level this table, right? 238 00:20:14,980 --> 00:20:19,440 But we don't have the control over it to actually make it do anything useful. 239 00:20:19,520 --> 00:20:24,240 So a lot of claims kind of fall short when it comes to the hardware. 240 00:20:24,240 --> 00:20:31,820 I think somebody mentioned a large-scale entangling coming out of China, a number of qubits that if they are fully entangled... 51. 241 00:20:31,820 --> 00:20:33,160 Yeah, it's very impressive. 242 00:20:33,160 --> 00:20:42,740 But now the next question that needs to be asked, can they exert full control over those 51 qubits to actually do something useful? 243 00:20:42,740 --> 00:20:46,980 Because if they can't, then I mean it comes down to the thing that I can point to. 244 00:20:46,980 --> 00:20:50,120 Look at my five million entangled qubits. 245 00:20:50,260 --> 00:20:54,580 Don't worry for how long they're entangled or whether I can control them or not, but they're right here. 246 00:20:54,880 --> 00:20:57,680 I'm pretty sure if you had five million entangled qubits, it doesn't matter a lot. 247 00:20:57,680 --> 00:21:00,040 I'm pretty sure it's right here. 248 00:21:00,620 --> 00:21:02,520 There's five million qubits right here. 249 00:21:04,900 --> 00:21:05,520 Questions? 250 00:21:05,520 --> 00:21:06,460 Yes, here, please. 251 00:21:06,480 --> 00:21:14,020 Basic question here, in part because you've already covered this, I came a little late, but what are the consequences of breaching quantum tech? 252 00:21:14,020 --> 00:21:24,940 I mean, you know, everybody talks about the advantages we have once we reach that stage, right, of using it, maybe commercializing it or something, but what are the consequences, the cold, like the cold hard truth of what it means? 253 00:21:26,880 --> 00:21:33,340 Also, to the gentleman on the right, did anybody tell you you look like Sheldon from the Big Bang Theory? 254 00:21:35,600 --> 00:21:37,040 It's way cooler. 255 00:21:37,460 --> 00:21:42,560 Yeah, I've been accused of talking like people don't understand what I'm saying. 256 00:21:43,240 --> 00:21:49,980 All right, so the question, to repeat the question, it's about what happens when we reach this state of a significant quantum advantage. 257 00:21:50,660 --> 00:21:53,680 Yeah, so a couple things will happen, right? 258 00:21:54,220 --> 00:22:05,560 If we have advantage and a large enough scale machine, we're at DEF CON, so there's the obvious thing that's going to happen, major cryptographic problems, and that all begins next year, by the way. 259 00:22:05,560 --> 00:22:11,660 NIST is going to publish this new standard, so starting next year, that's when the quantum apocalypse begins, because you have to start fixing it. 260 00:22:11,660 --> 00:22:16,220 Once the government says this is deprecated, you've got to fix it, whether you believe in quantum computers or not. 261 00:22:16,320 --> 00:22:18,320 So the apocalypse is here anyway. 262 00:22:18,320 --> 00:22:21,560 So that's going to happen one way or another, if you're the person fixing this stuff. 263 00:22:21,640 --> 00:22:25,900 What doesn't happen is we're going to start solving problems that we never thought we'd solve before. 264 00:22:26,380 --> 00:22:28,720 I think they're going to use less energy. 265 00:22:29,780 --> 00:22:39,560 Even though you imagine these refrigerators and all that, still, a quantum computer does a whole lot in a very quick period of time, with very little actual energy being expended. 266 00:22:39,720 --> 00:22:42,000 So that's the major thing that's going to happen. 267 00:22:42,000 --> 00:22:45,560 We're going to have these huge problems being solved that we were never able to tackle before. 268 00:22:45,560 --> 00:22:47,440 Things may be involved in the climate. 269 00:22:48,020 --> 00:22:50,400 Modeling chemicals that can take carbon out of the air. 270 00:22:50,400 --> 00:22:50,920 We don't know. 271 00:22:50,920 --> 00:22:54,360 It's like the use cases are almost unlimited when you get to that level. 272 00:22:54,360 --> 00:22:56,940 So it's a really exciting thing to look forward to. 273 00:22:57,640 --> 00:22:58,960 So is it a series? 274 00:23:00,300 --> 00:23:03,880 No, because I think we're going to start preparing for the cryptography. 275 00:23:03,880 --> 00:23:09,600 And Chrome is about to add, in version 116, they're about to add their hybrid post-quantum to that. 276 00:23:09,600 --> 00:23:12,280 They've already had it in AWS. 277 00:23:12,560 --> 00:23:14,780 So these things are happening already. 278 00:23:14,780 --> 00:23:17,920 I think if we get ahead of it, it'll be like with Y2K. 279 00:23:17,920 --> 00:23:18,980 Nothing happened. 280 00:23:19,120 --> 00:23:21,220 It was like, oh crap, it's okay. 281 00:23:21,260 --> 00:23:22,820 So it might be fine. 282 00:23:22,820 --> 00:23:23,760 Are you sure? 283 00:23:24,880 --> 00:23:26,240 That nothing happened? 284 00:23:29,040 --> 00:23:32,640 There are a couple applications that people think will come first. 285 00:23:33,300 --> 00:23:35,780 It was mentioned, quantum chemistry. 286 00:23:35,780 --> 00:23:47,640 So basically, one thing that a quantum computer is most likely good at, and again, we don't really know this until we're able to actually run it and prove it, but it's at simulating quantum systems. 287 00:23:47,980 --> 00:23:59,740 So this means things like, you know, building better batteries, because now you can simulate all the different electrolytes you would want to without actually have to go through and manufacture a battery. 288 00:24:00,140 --> 00:24:01,980 It was mentioned the climate impact. 289 00:24:01,980 --> 00:24:11,640 So this is usually around catalysts, usually based around transition metals that are very hard to simulate on a quantum level right now using traditional methods. 290 00:24:11,880 --> 00:24:21,500 But would require a modest, still a ridiculous compared to NISQ, but a modest for a quantum quantum computer number of cubits in order to actually go backward. 291 00:24:21,920 --> 00:24:23,300 But I'd say we don't know. 292 00:24:23,300 --> 00:24:29,060 It's like sitting in, you know, 1920 and saying, hey, what are we going to do with digital computers? 293 00:24:29,440 --> 00:24:34,720 I don't think we have any idea what, like, the equivalent of the quantum tender application is going to be. 294 00:24:34,860 --> 00:24:38,980 It's going to take, you know, a good amount of time to get there. 295 00:24:38,980 --> 00:24:40,660 We'll have a lot of thoughts, though. 296 00:24:42,240 --> 00:24:51,460 We have time for a few more questions before we vote on the proposition that they have been debating on this issue of quantum compute today. 297 00:24:51,460 --> 00:24:55,380 Is there any advantage by really knowing them? 298 00:24:55,500 --> 00:24:58,280 So here, please, first, and then we'll come back to you. 299 00:24:59,460 --> 00:25:18,080 What is your perspective on the investment of the relationship of quantum and quantum technology as a whole, including computing and energy as resources dwindle for building batteries and building computers in general? 300 00:25:18,080 --> 00:25:19,780 Do you see investment? 301 00:25:19,780 --> 00:25:22,620 How do you see that investment happening? 302 00:25:22,620 --> 00:25:28,160 Discuss, please, the investment and the opportunity between energy and quantum. 303 00:25:28,680 --> 00:25:29,520 Sure. 304 00:25:30,280 --> 00:25:39,940 So from the energy perspective, quantum computers don't operate faster than classical computers. 305 00:25:39,940 --> 00:25:42,120 They don't process everything in parallel. 306 00:25:42,120 --> 00:25:46,320 The best example is leveraging quantum mechanics. 307 00:25:46,320 --> 00:25:55,620 You can essentially encode your problem, your very hard problem, on a very complicated system and control it to get the answer. 308 00:25:55,620 --> 00:25:58,840 So you're sidestepping the difficult calculation. 309 00:25:58,840 --> 00:26:03,740 By difficult, I mean completely intractable by classical computation. 310 00:26:03,780 --> 00:26:07,380 And this is what all algorithms, quantum algorithms, are based on. 311 00:26:07,380 --> 00:26:08,780 So the hope is huge. 312 00:26:08,780 --> 00:26:15,760 The hope for, you know, resource scarcity is really massive. 313 00:26:15,760 --> 00:26:25,220 And it comes down to anything from optimization work, to quantum chemistry, to developing small molecule pharmaceuticals, and then all the way, all the way beyond that. 314 00:26:25,260 --> 00:26:31,840 Maybe if I understood your second part of the question was, like, what is the impact of manufacturing these things? 315 00:26:31,840 --> 00:26:34,600 Like, these things actually need to be made out of different materials. 316 00:26:34,860 --> 00:26:37,100 It really depends on the modality. 317 00:26:37,460 --> 00:26:39,360 Some things are really straightforward. 318 00:26:39,360 --> 00:26:41,720 They're silicon-based. 319 00:26:41,720 --> 00:26:47,060 There's, you know, no real super rare components to it. 320 00:26:47,060 --> 00:26:50,940 Other ones are based on much more scarce things. 321 00:26:51,140 --> 00:27:01,620 But I would say the impact that they will have is going to be so much greater than the resources that they're going to consume, compared to what classical computers are able to do today. 322 00:27:02,980 --> 00:27:05,980 And some of them could be made with, like, literally nothing. 323 00:27:05,980 --> 00:27:08,840 I mean, ions are, they're free. 324 00:27:08,840 --> 00:27:09,420 They're everywhere. 325 00:27:09,420 --> 00:27:10,200 You don't have to make them. 326 00:27:10,200 --> 00:27:11,100 They're already there. 327 00:27:11,520 --> 00:27:12,980 I don't know about ytterbium. 328 00:27:13,560 --> 00:27:15,060 Ytterbium, you know, whatever. 329 00:27:16,520 --> 00:27:17,300 There's some in here. 330 00:27:17,300 --> 00:27:18,580 I promise you there's some in here. 331 00:27:18,580 --> 00:27:20,020 I'm going to find it when we're done. 332 00:27:20,020 --> 00:27:20,840 I'll show you. 333 00:27:21,260 --> 00:27:22,340 It'll glow in my hands. 334 00:27:23,980 --> 00:27:28,960 So, yeah, so some of it depends, like you said, on the modality, what they're made of. 335 00:27:28,960 --> 00:27:36,100 And we're already using quantum computers in, like, simple optimization things for, like, how to wrap power, things like that. 336 00:27:36,100 --> 00:27:42,420 So these are, like, hybrid problems we're trying to solve, using some annealing and some other steps, and tensorizing, whatever. 337 00:27:42,440 --> 00:27:46,700 So we're very concerned with, like, using, applying this to power in general. 338 00:27:46,700 --> 00:27:48,000 Because, yeah, we've got a huge problem. 339 00:27:50,020 --> 00:27:51,800 One more question, then we vote. 340 00:27:52,620 --> 00:27:56,940 In terms of academia, let me just give you a 20 seconds context. 341 00:27:57,320 --> 00:28:04,120 ACM, IEEE, AAAI, Computer Science Curricula is the project that they're working for the next 10 years. 342 00:28:04,140 --> 00:28:04,780 Curricula. 343 00:28:04,780 --> 00:28:15,240 They're identified 18 knowledge areas, algorithms, operating systems, HCI, all the way to SEP, which is Society Ethics and Professionalism. 344 00:28:15,260 --> 00:28:16,780 You know, we're in DEF CON. 345 00:28:16,780 --> 00:28:17,740 We care about cyber. 346 00:28:17,740 --> 00:28:25,440 But at the same time, you're talking about green technologies and other aspects that quantum will have a big impact for the next 10 years. 347 00:28:25,440 --> 00:28:35,340 I was a little bit disappointed that the curriculum guidelines, they only have, like, less than two percent of learning outcomes and competencies in quantum. 348 00:28:35,340 --> 00:28:36,620 However, they're there. 349 00:28:36,760 --> 00:28:42,680 But, for example, cybersecurity is infused in the 18 knowledge areas. 350 00:28:42,680 --> 00:28:55,820 If I will ask you, and this is a question, if I ask you, what would be the top three computing areas that you should focus curriculum, like, heavily curriculum, what would those be in your experience? 351 00:28:55,820 --> 00:29:03,980 All right, what are the top three curriculum that you would focus on for computer science education overall? 352 00:29:06,160 --> 00:29:20,780 I would say, it's pretty straightforward for me, it would be building better quantum systems, writing better quantum algorithms, and absolutely machine learning, too, because it intersects so much. 353 00:29:20,780 --> 00:29:21,700 So, those are the three. 354 00:29:22,500 --> 00:29:24,720 I'm going to say the same way, but different. 355 00:29:24,720 --> 00:29:27,660 Linear algebra, linear algebra, and linear algebra. 356 00:29:30,460 --> 00:29:33,360 Yeah, of course. 357 00:29:33,360 --> 00:29:35,720 That's like saying you need the alphabet before you write something. 358 00:29:38,080 --> 00:29:41,440 I tried so hard to, like, keep linear algebra to a minimum. 359 00:29:45,060 --> 00:29:46,860 Ladies and gentlemen, it's time to vote. 360 00:29:46,860 --> 00:29:56,680 So, what I'm going to do is I'm going to say the proposition again, and then we will ask you to raise your hands if you support the proposition based on the arguments that you just heard. 361 00:29:56,900 --> 00:30:03,600 We are in the era of noisy intermediate scale intermediate scale quantum NISQ. 362 00:30:03,600 --> 00:30:05,260 This is the NISQ era. 363 00:30:05,440 --> 00:30:07,620 NISQ and the future of quantum advantage. 364 00:30:07,620 --> 00:30:16,840 This village believes the current state of NISQ is already enabling quantum advantage for those who know how to use these technologies. 365 00:30:16,840 --> 00:30:19,140 If you support that, raise your hand 366 00:30:22,230 --> 00:30:22,830 . 367 00:30:23,770 --> 00:30:25,570 I don't think it's already. 368 00:30:27,830 --> 00:30:29,470 That's the version I have. 369 00:30:30,570 --> 00:30:32,710 There's a lot of undecided. 370 00:30:32,870 --> 00:30:40,050 Yeah, if I could rephrase it, I would say that we don't need fault-tolerant for advantage, but I'm not saying we have an advantage now, for sure. 371 00:30:41,950 --> 00:30:43,790 Mark, how did that vote go, do you think? 372 00:30:44,130 --> 00:30:45,470 Oh, definitely against. 373 00:30:47,110 --> 00:30:50,590 Thank you for the three people who were reliably sort of going, yeah, sure. 374 00:30:52,730 --> 00:30:54,630 Well, we have captured this. 375 00:30:54,630 --> 00:30:59,650 I know there were a lot of other questions, so please, again, join our Discord server and keep asking your questions there. 376 00:30:59,650 --> 00:31:02,130 And with that, I want to say thanks to our debaters. 377 00:31:05,410 --> 00:31:06,670 Thanks, Mark. 378 00:31:06,810 --> 00:31:07,630 Thank you.
