WEBVTT 00:00:00.000 --> 00:00:02.480 Ever get that, like, I don't know, that itch? 00:00:02.980 --> 00:00:04.559 To really wrap your head around something that 00:00:04.559 --> 00:00:07.799 feels genuinely groundbreaking. Not just an incremental 00:00:07.799 --> 00:00:11.320 step, but a total game changer. Oh yeah. The 00:00:11.320 --> 00:00:13.759 kind of tech that could rewrite the rules in 00:00:13.759 --> 00:00:16.399 ways we can barely even imagine. Definitely. 00:00:16.539 --> 00:00:18.100 I think a lot of our listeners are right there 00:00:18.100 --> 00:00:20.600 with you. They want to understand those big leaps, 00:00:20.679 --> 00:00:22.660 those things that are really pushing the boundaries, 00:00:22.960 --> 00:00:25.059 but without getting bogged down in all the technical 00:00:25.059 --> 00:00:27.460 details. Well, you've come to the right place, 00:00:27.640 --> 00:00:30.670 this deep dive. We're tackling a topic that fixed 00:00:30.670 --> 00:00:34.530 that bill to a T quantum computing. It's mind 00:00:34.530 --> 00:00:36.909 blowing stuff, really. We've got some amazing 00:00:36.909 --> 00:00:39.609 material to work with today, stuff that really 00:00:39.609 --> 00:00:41.369 gets into the core of it all. So we'll break 00:00:41.369 --> 00:00:44.729 down the fundamental principles, the very essence 00:00:44.729 --> 00:00:47.990 of what makes quantum computing tick. And then 00:00:47.990 --> 00:00:50.409 we'll explore the incredible possibilities it 00:00:50.409 --> 00:00:53.229 opens up across a whole spectrum of scientific 00:00:53.229 --> 00:00:55.609 disciplines. And it's not just about the science 00:00:55.609 --> 00:00:58.299 itself, right? Absolutely not. Our sources really 00:00:58.299 --> 00:01:01.380 highlight this intense global race that's underway. 00:01:02.100 --> 00:01:05.480 A strategic competition with nations vying for 00:01:05.480 --> 00:01:07.980 dominance in this field. It's a big deal. And 00:01:07.980 --> 00:01:10.200 of course, we can't ignore the cybersecurity 00:01:10.200 --> 00:01:12.760 challenges that quantum computing could unleash. 00:01:13.140 --> 00:01:16.280 Very real concerns there for sure. So our mission, 00:01:16.760 --> 00:01:19.540 pretty straightforward, to give you a solid understanding 00:01:19.540 --> 00:01:22.560 of the core concepts of quantum computing. That's 00:01:22.560 --> 00:01:25.340 the foundation. We want you to come away appreciating 00:01:25.340 --> 00:01:28.239 the potential of this technology to transform 00:01:28.239 --> 00:01:31.439 industries and get a grasp on those geopolitical 00:01:31.439 --> 00:01:34.200 and security implications. Those are crucial, 00:01:34.340 --> 00:01:37.319 no doubt. So let's unpack this. What is quantum 00:01:37.319 --> 00:01:39.359 computing? I mean, the name itself sounds like 00:01:39.359 --> 00:01:41.359 something out of science fiction. Yeah, it can 00:01:41.359 --> 00:01:43.120 seem a little intimidating, but let's start with 00:01:43.120 --> 00:01:46.700 what we know. Classical computers, the ones we 00:01:46.700 --> 00:01:50.159 use every day, they operate on bits, which are 00:01:50.159 --> 00:01:51.920 essentially like on off switches. It's either 00:01:51.920 --> 00:01:54.329 a one or a zero. Right, just like a light switch, 00:01:54.370 --> 00:01:57.010 either on or off. Exactly. And when they solve 00:01:57.010 --> 00:01:59.750 problems, they do it step by step. Think of it 00:01:59.750 --> 00:02:02.769 like navigating a maze, trying each path one 00:02:02.769 --> 00:02:05.250 at a time until you find the way out. Okay, very 00:02:05.250 --> 00:02:07.670 methodical, one possibility at a time. Right. 00:02:08.150 --> 00:02:10.449 Now quantum computers, they work completely differently. 00:02:10.610 --> 00:02:12.729 Their building blocks are called qubits, which 00:02:12.729 --> 00:02:15.250 stands for quantum bits. And this is where the 00:02:15.250 --> 00:02:18.250 quantum leap happens. A qubit can exist in what's 00:02:18.250 --> 00:02:21.479 called superposition. Superposition. I'm already 00:02:21.479 --> 00:02:23.840 feeling a little lost. Think of it this way. 00:02:24.460 --> 00:02:27.360 That light switch we talked about. In superposition, 00:02:27.639 --> 00:02:30.740 it's not just on or off. It's both simultaneously. 00:02:31.219 --> 00:02:33.159 It's like it's flickering between those states. 00:02:33.280 --> 00:02:36.020 So it's not either. It's both at the same time. 00:02:36.159 --> 00:02:38.319 That's the essence of it. And this ability to 00:02:38.319 --> 00:02:41.240 be in multiple states at once is what gives quantum 00:02:41.240 --> 00:02:44.740 computers their potential power. Imagine, instead 00:02:44.740 --> 00:02:47.659 of trying each path in that maze one by one, 00:02:48.000 --> 00:02:50.199 a quantum computer could explore all possible 00:02:50.199 --> 00:02:53.159 paths simultaneously. It's like having a million 00:02:53.159 --> 00:02:54.939 computers working on the problem at the same 00:02:54.939 --> 00:02:57.259 time. Whoa! So we're not just talking about speed 00:02:57.259 --> 00:02:59.099 here, are we? It's a totally different way of 00:02:59.099 --> 00:03:01.479 approaching problems. Exactly. Our sources mentioned 00:03:01.479 --> 00:03:03.340 some calculations that would take today's most 00:03:03.340 --> 00:03:06.000 powerful supercomputers millions of years to 00:03:06.000 --> 00:03:08.620 complete. A quantum computer might be able to 00:03:08.620 --> 00:03:11.310 do those same calculations in just minutes. That's 00:03:11.310 --> 00:03:14.210 not just a speed boost. It's like rewinding time. 00:03:14.550 --> 00:03:17.710 Right. And as Olivia Lanes, a researcher at IBM, 00:03:17.789 --> 00:03:20.330 put it, this isn't just about making existing 00:03:20.330 --> 00:03:23.330 computers better. It's an entirely new way of 00:03:23.330 --> 00:03:25.750 computing that mirrors how the universe operates 00:03:25.750 --> 00:03:29.090 at the atomic and molecular level. OK, so it's 00:03:29.090 --> 00:03:31.150 not just about faster spreadsheets or better 00:03:31.150 --> 00:03:33.870 AI. It's about tapping into the fundamental laws 00:03:33.870 --> 00:03:37.150 of physics. Exactly. And that brings us to the 00:03:37.150 --> 00:03:39.620 scientific promise. So what are some of the mind 00:03:39.620 --> 00:03:42.020 -blowing applications of this technology? Imagine 00:03:42.020 --> 00:03:45.020 being able to simulate nature at the atomic level. 00:03:45.479 --> 00:03:48.419 Think designing new drugs, molecule by molecule, 00:03:48.699 --> 00:03:51.060 or creating entirely new materials with properties 00:03:51.060 --> 00:03:54.219 we can only dream of. Stronger, lighter, more 00:03:54.219 --> 00:03:56.780 efficient, even game -changing breakthroughs 00:03:56.780 --> 00:03:59.099 in battery technology. It sounds almost like 00:03:59.099 --> 00:04:01.780 science fiction. It does, doesn't it? But our 00:04:01.780 --> 00:04:04.240 source, Olivia Lanes, had a great analogy. She 00:04:04.240 --> 00:04:06.240 compared the advent of quantum computing to the 00:04:06.240 --> 00:04:08.810 invention of the telescope. Just like the telescope 00:04:08.810 --> 00:04:10.509 allowed us to see the universe in a completely 00:04:10.509 --> 00:04:12.949 new way, quantum computers could give us this 00:04:12.949 --> 00:04:15.469 incredible insight into the building blocks of 00:04:15.469 --> 00:04:18.730 reality. That's a powerful comparison. But our 00:04:18.730 --> 00:04:20.470 source also mentioned that quantum computers 00:04:20.470 --> 00:04:23.389 aren't quite ready to outperform classical supercomputers 00:04:23.389 --> 00:04:25.829 in practical applications. What's the holdup? 00:04:26.069 --> 00:04:28.089 The biggest hurdle right now is maintaining the 00:04:28.089 --> 00:04:30.889 stability of those qubits. They are incredibly 00:04:30.889 --> 00:04:33.670 sensitive to any external interference. So even 00:04:33.670 --> 00:04:36.069 a slight change in temperature or a tiny vibration 00:04:36.069 --> 00:04:38.569 could throw things off. Absolutely. It's like 00:04:38.569 --> 00:04:40.810 trying to balance a spinning coin on its edge. 00:04:41.209 --> 00:04:44.730 The slightest nudge will topple it over. So what 00:04:44.730 --> 00:04:46.850 does one of these quantum computers actually 00:04:46.850 --> 00:04:49.930 look like? I have this image of a sleek, futuristic 00:04:49.930 --> 00:04:53.089 box. Well, the reality is a bit different. Our 00:04:53.089 --> 00:04:56.209 source described the IBM Quantum System 2 and 00:04:56.209 --> 00:04:59.040 its core component, the Heron chip. It's actually 00:04:59.040 --> 00:05:01.680 incredibly small, 133 qubits that can fit in 00:05:01.680 --> 00:05:04.579 the palm of your hand. Wow, that's amazing. So 00:05:04.579 --> 00:05:06.959 much potential in such a tiny package. But to 00:05:06.959 --> 00:05:08.779 keep those qubits stable, they need to be kept 00:05:08.779 --> 00:05:11.319 at extremely low temperatures, just a fraction 00:05:11.319 --> 00:05:14.639 of a degree above absolute zero. Colder than 00:05:14.639 --> 00:05:16.800 the cosmic microwave background radiation, which 00:05:16.800 --> 00:05:19.579 is already incredibly cold. So this incredible 00:05:19.579 --> 00:05:22.199 technology relies on being the coldest thing 00:05:22.199 --> 00:05:25.040 in the universe. That's quite paradox. It is, 00:05:25.120 --> 00:05:28.000 isn't it? Now, let's talk about the geopolitical 00:05:28.000 --> 00:05:31.360 dimension of this, the quantum arms race. Our 00:05:31.360 --> 00:05:33.839 sources paint a picture of intense competition, 00:05:34.100 --> 00:05:37.680 especially between the US and China. Yes, the 00:05:37.680 --> 00:05:41.160 stakes are incredibly high. IBM, for example, 00:05:41.540 --> 00:05:44.079 is investing billions of dollars annually in 00:05:44.079 --> 00:05:46.620 quantum computing research and development. They're 00:05:46.620 --> 00:05:48.540 not just focused on building a better computer, 00:05:48.920 --> 00:05:51.370 but on creating an entire quantum industry. And 00:05:51.370 --> 00:05:53.589 while they keep tabs on their competitors, they're 00:05:53.589 --> 00:05:55.470 drawing a line when it comes to collaboration, 00:05:55.790 --> 00:05:57.529 especially with Chinese companies. That's right. 00:05:57.649 --> 00:05:59.610 They have a strict policy against it, citing 00:05:59.610 --> 00:06:02.569 national security concerns. This really highlights 00:06:02.569 --> 00:06:04.730 the strategic importance that governments are 00:06:04.730 --> 00:06:07.089 placing on quantum technology. It's not just 00:06:07.089 --> 00:06:09.670 about science anymore. It's about national security 00:06:09.670 --> 00:06:11.910 and global leadership. It seems like China is 00:06:11.910 --> 00:06:14.629 pulling out all the stops in this race. Oh, absolutely. 00:06:15.250 --> 00:06:18.209 They've invested over $15 billion, more than 00:06:18.209 --> 00:06:20.829 three times any other country. They have established 00:06:20.829 --> 00:06:23.949 numerous research institutes dedicated to quantum 00:06:23.949 --> 00:06:26.790 technologies and currently hold over half of 00:06:26.790 --> 00:06:29.209 all the patents in this field. That's a significant 00:06:29.209 --> 00:06:32.350 lead. What's the U .S. doing to keep up? Well, 00:06:32.569 --> 00:06:34.870 they've implemented export controls to prevent 00:06:34.870 --> 00:06:37.250 the most advanced U .S. quantum technologies 00:06:37.250 --> 00:06:39.879 from being shared with China. and they've passed 00:06:39.879 --> 00:06:42.660 the CHEPS and Science Act to increase funding 00:06:42.660 --> 00:06:45.040 for research and development in critical areas 00:06:45.040 --> 00:06:47.779 like quantum computing. It's a clear sign that 00:06:47.779 --> 00:06:49.839 the US is taking this competition seriously. 00:06:50.199 --> 00:06:52.220 It sounds like we're on the verge of a technological 00:06:52.220 --> 00:06:54.800 revolution with major implications for global 00:06:54.800 --> 00:06:57.060 power dynamics. There's no doubt about it. But 00:06:57.060 --> 00:06:59.100 apart from the geopolitical concerns, there's 00:06:59.100 --> 00:07:01.740 also the very real threat that quantum computing 00:07:01.740 --> 00:07:04.899 poses to cybersecurity, right? This is a huge 00:07:04.899 --> 00:07:07.300 concern. Our source explained that much of our 00:07:07.300 --> 00:07:10.100 online security, everything from banking to email, 00:07:10.600 --> 00:07:13.000 relies on encryption. Right, those secret codes 00:07:13.000 --> 00:07:15.379 that scramble our data and keep it safe from 00:07:15.379 --> 00:07:18.699 prying eyes. Exactly. And a common encryption 00:07:18.699 --> 00:07:21.879 method, called RSA, is based on the difficulty 00:07:21.879 --> 00:07:24.569 of factoring large prime numbers. Right, like 00:07:24.569 --> 00:07:28.470 if you multiply 17 by 31, you get 527. That's 00:07:28.470 --> 00:07:32.470 easy. But if you only know the 527, figuring 00:07:32.470 --> 00:07:35.110 out the original numbers is a much harder problem. 00:07:35.350 --> 00:07:37.449 Right. Now imagine those numbers being hundreds 00:07:37.449 --> 00:07:40.930 of digits long. For classical computers, factoring 00:07:40.930 --> 00:07:43.290 those massive numbers would take trillions of 00:07:43.290 --> 00:07:45.350 years, which is why this encryption method is 00:07:45.350 --> 00:07:47.819 so secure. But quantum computers could change 00:07:47.819 --> 00:07:50.360 that, couldn't they? Yes. Because of their ability 00:07:50.360 --> 00:07:52.939 to perform calculations simultaneously, they 00:07:52.939 --> 00:07:54.860 could potentially crack these codes in a fraction 00:07:54.860 --> 00:07:57.360 of the time. We're talking about reducing a problem 00:07:57.360 --> 00:08:00.000 that would take trillions of years to mere minutes. 00:08:00.160 --> 00:08:02.000 That's a terrifying thought. I mean, all our 00:08:02.000 --> 00:08:03.800 sensitive data could be vulnerable overnight. 00:08:04.160 --> 00:08:06.699 Exactly. Our source highlighted the concerns 00:08:06.699 --> 00:08:09.540 within the banking industry. Imagine what would 00:08:09.540 --> 00:08:11.939 happen if trillions of dollars worth of transactions 00:08:11.939 --> 00:08:15.139 were suddenly exposed. It would be chaos. Identity 00:08:15.139 --> 00:08:17.699 theft, financial losses, a complete loss of trust 00:08:17.699 --> 00:08:20.459 in online systems. And it gets even scarier. 00:08:20.939 --> 00:08:24.060 There's something called Store Now Decrypt Later. 00:08:24.879 --> 00:08:28.120 Think about it. Malicious actors could be collecting 00:08:28.120 --> 00:08:31.420 encrypted data right now, knowing that they can 00:08:31.420 --> 00:08:33.379 crack it open later when they have access to 00:08:33.379 --> 00:08:35.980 powerful enough quantum computers. So even our 00:08:35.980 --> 00:08:37.919 past communications, the things we think are 00:08:37.919 --> 00:08:40.340 secure today, could be vulnerable in the future. 00:08:40.519 --> 00:08:42.789 That's the threat. It's not just about protecting 00:08:42.789 --> 00:08:44.549 data in the future, it's about protecting the 00:08:44.549 --> 00:08:47.230 data we've already generated. This really emphasizes 00:08:47.230 --> 00:08:49.990 the need for new quantum -resistant security 00:08:49.990 --> 00:08:52.389 measures. Absolutely. And one promising approach 00:08:52.389 --> 00:08:54.649 that our sources discussed is called quantum 00:08:54.649 --> 00:08:58.009 key distribution, or QKD. Okay, that sounds very 00:08:58.009 --> 00:09:00.210 high -tech. How does it work? It leverages a 00:09:00.210 --> 00:09:02.509 fundamental principle of quantum mechanics. The 00:09:02.509 --> 00:09:05.269 act of observing a quantum particle changes its 00:09:05.269 --> 00:09:09.039 state. So in 2KB, they use single photons, particles 00:09:09.039 --> 00:09:11.759 of light, to generate and transmit encryption 00:09:11.759 --> 00:09:14.220 keys. OK, I'm following so far. Now if someone 00:09:14.220 --> 00:09:16.720 tries to intercept those photons to eavesdrop 00:09:16.720 --> 00:09:19.440 on the key, that very active observation will 00:09:19.440 --> 00:09:22.100 alter the photons, making the eavesdropping attempt 00:09:22.100 --> 00:09:24.480 detectable. It's like those alarms in stores. 00:09:24.539 --> 00:09:26.799 If you break the beam, the alarm goes off. That's 00:09:26.799 --> 00:09:29.279 a great analogy. And because any interception 00:09:29.279 --> 00:09:31.779 is immediately detectable, the legitimate parties 00:09:31.779 --> 00:09:34.179 can abandon the compromised key and generate 00:09:34.179 --> 00:09:37.179 a new, secure one. So it's like having an unbreakable 00:09:37.179 --> 00:09:41.190 encryption system. In essence, yes. And Toshiba 00:09:41.190 --> 00:09:43.870 has already developed a QKD device that's being 00:09:43.870 --> 00:09:47.330 tested on existing fiber optic networks. They've 00:09:47.330 --> 00:09:49.250 successfully transmitted sensitive financial 00:09:49.250 --> 00:09:52.210 data, medical scans, and even government data 00:09:52.210 --> 00:09:54.250 across London. So this isn't just theoretical 00:09:54.250 --> 00:09:56.769 anymore, it's being put into practice. Exactly. 00:09:57.309 --> 00:09:59.549 And there's a real sense of urgency to develop 00:09:59.549 --> 00:10:01.529 and implement these quantum -resistant security 00:10:01.529 --> 00:10:04.129 measures. Especially since our sources estimated 00:10:04.129 --> 00:10:06.409 that cryptographically relevant quantum computers 00:10:06.409 --> 00:10:08.870 could emerge within the next five to seven years. 00:10:09.799 --> 00:10:11.860 frame we're looking at. It's no longer a matter 00:10:11.860 --> 00:10:15.259 of if, but when. And it's not just about individual 00:10:15.259 --> 00:10:18.159 companies or banks. National security is at stake 00:10:18.159 --> 00:10:20.700 here. Our sources highlighted other countries 00:10:20.700 --> 00:10:23.509 making significant progress in this area. like 00:10:23.509 --> 00:10:26.269 China, which launched a quantum communication 00:10:26.269 --> 00:10:29.690 satellite back in 2016 and is building a national 00:10:29.690 --> 00:10:32.190 quantum network. Right. And Singapore is focusing 00:10:32.190 --> 00:10:35.049 on developing commercially viable, unhackable 00:10:35.049 --> 00:10:38.169 networks using nanosatellites, which are much 00:10:38.169 --> 00:10:40.929 smaller and more cost effective than China's 00:10:40.929 --> 00:10:43.649 larger satellite. It sounds like a global race 00:10:43.649 --> 00:10:45.990 to secure the future of communication. You could 00:10:45.990 --> 00:10:48.149 say that. Looking at the future of quantum computing 00:10:48.149 --> 00:10:50.710 as a whole, our sources talked about the delicate 00:10:50.710 --> 00:10:53.129 balance between international coll... collaboration 00:10:53.129 --> 00:10:56.470 and the rising geopolitical tensions. Absolutely. 00:10:56.990 --> 00:10:59.409 The early days of quantum computing saw a lot 00:10:59.409 --> 00:11:01.690 of collaboration between researchers and companies 00:11:01.690 --> 00:11:04.190 from different countries. But now, with the U 00:11:04.190 --> 00:11:06.809 .S.-China rivalry intensifying, things are getting 00:11:06.809 --> 00:11:09.720 more complicated. So on the one hand we have 00:11:09.720 --> 00:11:11.799 this incredible technology that could benefit 00:11:11.799 --> 00:11:14.279 all of humanity, but on the other there's this 00:11:14.279 --> 00:11:16.799 fear that it could be used for harmful purposes. 00:11:17.120 --> 00:11:20.279 It's a difficult situation. The U .S. has implemented 00:11:20.279 --> 00:11:22.940 export controls to protect its technological 00:11:22.940 --> 00:11:26.600 advantage, but there's a concern that these restrictions 00:11:26.600 --> 00:11:30.279 might stifle innovation. It's a classic dilemma. 00:11:30.879 --> 00:11:33.460 How do we balance national security with the 00:11:33.460 --> 00:11:35.820 potential benefits of scientific progress? And 00:11:35.820 --> 00:11:38.039 there are no easy answers. It seems like the 00:11:38.039 --> 00:11:40.019 scientific community is trying to stay focused 00:11:40.019 --> 00:11:42.840 on the positive potential of quantum computing. 00:11:43.200 --> 00:11:45.960 They are. They see it as a tool that could revolutionize 00:11:45.960 --> 00:11:48.740 medicine, mercurial science, and our understanding 00:11:48.740 --> 00:11:50.740 of the universe. Like that analogy with the telescope, 00:11:50.759 --> 00:11:53.019 right? Exactly. One of our sources, Professor 00:11:53.019 --> 00:11:54.840 Hannah Fry, made a really interesting point. 00:11:54.879 --> 00:11:57.059 She said that we should think of quantum computing 00:11:57.059 --> 00:11:59.840 not just as a race, but as the development of 00:11:59.840 --> 00:12:02.720 a powerful new scientific instrument. So instead 00:12:02.720 --> 00:12:06.009 of focusing on who wins the race, we should focus 00:12:06.009 --> 00:12:09.809 on how we can use this tool to benefit everyone. 00:12:09.950 --> 00:12:12.509 That's the ideal, isn't it? To use this technology 00:12:12.509 --> 00:12:15.269 for the greater good. So, to wrap things up, 00:12:15.710 --> 00:12:18.830 we've explored how quantum computing works, its 00:12:18.830 --> 00:12:22.009 potential to revolutionize various fields, and 00:12:22.009 --> 00:12:24.509 the very real cybersecurity threats it poses. 00:12:25.070 --> 00:12:27.649 We've also discussed the geopolitical tensions 00:12:27.649 --> 00:12:30.490 surrounding this technology and the race to develop 00:12:30.490 --> 00:12:32.830 quantum -resistant security measures. It's a 00:12:32.830 --> 00:12:35.350 lot to take in, but it's incredibly exciting 00:12:35.350 --> 00:12:37.769 and a little bit daunting at the same time. We're 00:12:37.769 --> 00:12:40.009 on the verge of a technological revolution that 00:12:40.009 --> 00:12:42.250 could change the world as we know it. And as 00:12:42.250 --> 00:12:45.049 quantum technology continues to evolve, we need 00:12:45.049 --> 00:12:48.070 to ask ourselves some tough questions. How do 00:12:48.070 --> 00:12:50.769 we balance national security concerns with the 00:12:50.769 --> 00:12:53.149 need for international scientific collaboration? 00:12:53.669 --> 00:12:56.230 How do we ensure that the benefits of this technology 00:12:56.230 --> 00:12:59.769 are shared equitably? And how do we protect individual 00:12:59.769 --> 00:13:02.350 privacy in a world where encryption can be broken? 00:13:02.950 --> 00:13:05.110 It's a lot to ponder, but these are the questions 00:13:05.110 --> 00:13:07.549 we need to be asking as we enter this new era 00:13:07.549 --> 00:13:09.889 of quantum computing. Because the choices we 00:13:09.889 --> 00:13:12.330 make today will shape the world of tomorrow. 00:13:12.590 --> 00:13:14.190 And that's something for all of us to consider. 00:13:14.570 --> 00:13:16.570 Absolutely. Thanks for joining us on this deep 00:13:16.570 --> 00:13:18.470 dive into the world of quantum computing. We'll 00:13:18.470 --> 00:13:19.090 see you next time.
