Google's Quantum Chip Just Broke Reality (You Won't Believe What It Can Do!)

so something crazy just happened in AI Google announced a new Quantum chip called Willow and it's actually completely changing the game in two mindblowing ways first let me explain what makes Willow different from your regular computer your phone your laptop even the most powerful supercomputers they all work basically the same way like a fast super calculator using ones and zeros but here's the difference with Willow it actually uses the weird rules of quantum physics which are the same rules that govern how atoms work now here's where it gets really interesting most people think that when you make computers bigger or more complex they're more likely to make mistakes like how a longer chain has more chances to break right and that's exactly what made quantum computers so tricky to build in the past but Willow it actually does something that scientists have been trying to achieve for almost 30 years and when you make computers bigger or more complex they tend to get Messier kind of like how a bigger house has a lot more things that can go wrong and with regular computers the more parts mean more chances for errors and that's just how things usually work but with Willow it completely flips this rule on its head instead of getting worse with size it actually gets better at fixing its own mistakes the bigger it gets it's like having a house that becomes easier to clean the more rooms you add it actually sounds impossible but that's exactly what Google has managed to do and this image illustrates one of Willow's biggest breakthroughs so let me just break this down for you guys think of it like building an increasingly larger teams of workers which are the cubits who can catch each other's mistakes the 3X3 grid which is of course in red is like a team of small workers that can handle fixing one mistake at a time it's basic proof that the system works the 5x5 grid is scaled up to 49 workers which can now handle two mistakes simultaneously and it shows the system works better as it gets bigger and the 7x7 grid is a big team of 97 workers that can handle three mistakes at once and it proves that bigger equals more reliable and not less and the Revolutionary part is that normally when you add more cubits which are you know in this case workers you get more errors but Willow does the opposite the bigger the grid gets the better it handles errors it's kind of like having a team where you add more people and you reduce mistakes instead of creating chaos the yellow connections between the colored squares show how the cubits work together to catch and correct errors kind of like how a safety net that gets stronger as it gets bigger now with all of that being said why is this even a big deal well imagine you had a car that got better gas mileage the larger you made it that's not how things are supposed to work usually bigger cars use more gas not less but in Willow's case making it bigger actually makes it more efficient and more reliable and the really exciting part is that it's not just a small Improvement they managed to show that Willow can keep its Quantum properties even as it scales up and in the quantum World keeping things Quantum is incredibly hard because these systems are super fragile it's like trying to keep a soap bubble intact the bigger you make it the more likely it is to pop but Willow somehow gets more stable instead and what's crazy about all of this is wait until you hear about how fast this works with a random circuit sampling Benchmark the results are pretty surprising by our best estimates a calculation that takes Willow under 5 minutes would take the fastest supercomputer 10 to the 25 years that's a one with 25 zeros following it or a time scale way longer than the age of the universe this result highlights the exponentially growing gap between classical and Quantum computation for certain applications now one of the biggest fears that many people have is the fact that this could potentially crack Bitcoin but that isn't actually true when you actually think about what Bitcoin is it's like trying to break into a massive bank vault with millions of possible combinations current computers would need centuries to try all of these combinations now Willow Google's new quantum computer is incredibly powerful but in a very specific way it's like having a race car that can only drive on one specific track sure it's blindingly fast on that track but it can't drive on regular roads to break Bitcoin you'd actually need a quantum computer that's quite like a Swiss army knife with way more tools which are thousands of more cubits than Willows 105 it actually also need a lot better Precision Willow still makes way too many mistakes and specific capabilities that Willow doesn't have it's kind of like Willow is amazing at solving complex puzzles in record time but breaking Bitcoin security is a completely different game like trying to use a Ferrari to crack a safe no matter how fast that fer is it's just not the

right tool for the job and I wanted to actually include this in the video because I saw the fact that there were numerous people who were stating that look it's completely over for Bitcoin and that just simply isn't the case now one of the most interesting things that I actually saw was this and I didn't see most people talking about this but this is a mindbending concept okay so when Google's Willow quantum computer solves a problem in 5 minutes that would take a regular supercomputer 10 septian years is it raises a fascinating question how is this even possible where is all that computation actually happening one explanation first proposed by the physicist David D is that quantum computers might actually be tapping into the parallel universes to do their calculations so this is how you can kind of visualize that or even think about that imagine you need to solve a maze a regular computer would try to solve One path at a time like a person walking through a maze now basically what a quantum computer does is that it tries all possible path simultaneously as if copies of itself and parallel universes were each trying different paths and then somehow the right answer emerges in our universe and this creates something like a giant Quantum parallel processing system where the computation isn't just happening in our universe but across many universes at once it's like having infinite versions of yourself solving the same problem in slightly different ways and then getting the answer from all of them at once now this isn't proven it's a theoretical explanation for how quantum computers can perform certain calculations so impossibly fast the fact that Willow can do calculations that would take longer than the universe has existed suggests something rather strange and fascinating is happening behind the scenes now you might be also wondering what exactly is next basically you can see we've got the quantum road map now the Milestone number one is beyond the classical this is where you're proving classical computers can do thing regular computers can't Willow has already achieved this by doing calculations that would take regular supercomputers 10 septian years like proving you can actually build a plane that actually flies while everyone is still making cars now Milestone 2 is where you've got Quantum error correction current quantum computers are very eror prone like a car that breaks down every few miles and they're working on making the QQ bits Quantum bits more reliable just like developing an engine that can self repair while running and the Breakthrough with Willow that we recently had showing that adding more cubits actually reduces the errors instead of creating more is basically way you can think of it as you know more backup systems you know fewer mistakes now this is where we start to get into the future Milestone 3 building a long lived logical Cubit the current cubits that we have die really quickly and they're trying to make cubits stay stable for much longer basically like developing a battery that lasts for months instead of minutes then of course The Logical gate is where you're building the building box of the quantum calculations and without reliable Gates complex Quantum programs won't work and once you have all of these parts you've got the engineering scale up it's like going from building one perfect engine to building thousands and of course that's when we get to Milestone 6 the final quantum computer that can solve real world problems combines all previous Milestones into one working system like having a complete aircraft carrier instead of just a prototype Jet and this is where we get to that sci-fi stuff where we have super intelligence artificial super intelligence some crazy stuff I think this entire thing is just showing us how quickly the AI space the quantum space is completely moving and I can't wait to share more progress when Google will have more to offer so with that being said if you enjoyed this video I'll see you in the next one
