00:00Right now, a revolution is happening in labs across the world.

00:03Scientists are harnessing the bizarre properties of quantum mechanics

00:07to build computers that could change everything.

00:09From breaking unbreakable codes to simulating molecules for new drugs,

00:14quantum computers promise to solve problems our current machines can't touch.

00:18But here's the kicker.

00:19Most people have no idea how far we've come or what's coming next.

00:23In this video, we're pulling back the curtain on the eight stages of quantum computing.

00:26You'll learn exactly where we are now and what's just around the corner.

00:29Get ready to dive into a world where particles can be in two places at once

00:33and information travels faster than light.

00:36By the end of this video, you'll understand why tech giants are pouring billions into this technology

00:40and how it could impact your life sooner than you think.

00:43Let's jump in.

00:44Stage one, the quantum spark.

00:46In 1981, physicist Richard Feynman threw down the gauntlet.

00:49He proposed a radical idea, using quantum systems to simulate other quantum systems.

00:54This was the quantum spark that ignited a technological revolution.

00:57But why was this such a big deal?

00:59Traditional computers struggle with quantum problems.

01:02They're like trying to paint a 3D picture on a 2D canvas.

01:05You're always missing something.

01:06Quantum computers, on the other hand, speak the language of the quantum world fluently.

01:10This isn't just theoretical.

01:12In 2019, Google's quantum computer performed a calculation in 200 seconds

01:17that would take the world's most powerful supercomputer 10,000 years.

01:21That's not just faster, it's in a whole different league.

01:24The quantum spark has been lit and there's no putting it out.

01:27But this is just the beginning.

01:28What comes next will blow your mind.

01:30Stage two, qubits, the building blocks of quantum power.

01:34Welcome to the world of qubits, where the rules of classical computing go out the window.

01:38Unlike traditional bits that can only be zero or one, qubits can be both at the same time.

01:43It's like having a coin that's heads and tails simultaneously.

01:45But here's where it gets really interesting.

01:47Two qubits can hold four states at once, three can hold eight, and so on.

01:51It doubles with each additional qubit.

01:53By the time you get to 300 qubits,

01:55you're dealing with more states than there are atoms in the observable universe.

01:59In 2021, IBM unveiled its 127-qubit processor, Eagle.

02:04That might not sound like much, but it's a huge leap forward.

02:06With each qubit added, the computing power grows exponentially.

02:10The race is on to create more stable qubits.

02:12Scientists are exploring everything from superconducting circuits to trapped ions.

02:17Each approach has its pros and cons, but they're all pushing towards the same goal,

02:21harnessing the full power of quantum mechanics.

02:23As we move to the next stage, remember this.

02:26Qubits are just the beginning.

02:27What comes next will reshape our understanding of computation itself.

02:31Stage 3, quantum supremacy, the tipping point.

02:34Quantum supremacy.

02:35It sounds like something out of a sci-fi movie, but it's very real.

02:39This is the point where a quantum computer can solve a problem

02:41that no classical computer can solve in any feasible amount of time.

02:45In 2019, Google claimed to have achieved quantum supremacy

02:49with its 53-qubit Sycamore processor.

02:52They solved a specific problem in 200 seconds,

02:55a task they estimated would take the world's most powerful supercomputer 10,000 years.

02:59But here's the twist.

03:00IBM disputed this claim, saying their classical supercomputer

03:04could solve the problem in 2.5 days.

03:06This controversy highlights a crucial point.

03:08Quantum supremacy isn't a single clear-cut moment.

03:10It's a moving target, constantly being redefined

03:13as both quantum and classical computers improve.

03:16The implications of true quantum supremacy are staggering.

03:19It could lead to breakthroughs in fields like cryptography,

03:22drug discovery, and financial modeling.

03:24But it also poses risks.

03:26A sufficiently powerful quantum computer

03:28could break most of the encryption we use today,

03:30potentially compromising global digital security.

03:33Stage 4, quantum error correction, taming the quantum beast.

03:37Imagine trying to build a sandcastle while waves constantly wash away your work.

03:41That's what it's like working with quantum computers.

03:43Qubits are incredibly fragile,

03:44and the slightest disturbance can cause errors in calculations.

03:47This is where quantum error correction comes in.

03:49It's like building a seawall to protect our quantum sandcastle.

03:52By using multiple physical qubits to represent a single logical qubit,

03:56we can detect and correct errors as they happen.

03:59In 2021, a team at Google demonstrated a logical qubit

04:02with a lower error rate than the physical qubits it was made from.

04:05This was a major milestone,

04:07proving that quantum error correction isn't just theoretical, it's achievable.

04:11But here's the catch.

04:12Current methods require about 1,000 physical qubits for each logical qubit.

04:16That's why companies like IBM and Google

04:18are racing to build processors with thousands of qubits.

04:21As we crack the code on quantum error correction,

04:23we're opening the door to longer, more complex quantum computations.

04:27This isn't just an incremental improvement,

04:29it's the key to unlocking the full potential of quantum computing.

04:33And speaking of potential, wait until you see what's coming in the next stage.

04:37It's where quantum computing starts to change the world as we know it.

04:40Stage 5, quantum advantage, from theory to practice.

04:43We've talked about quantum supremacy,

04:45but quantum advantage is where the rubber really meets the road.

04:48This is the point where quantum computers can solve real-world problems

04:52faster, cheaper, or more efficiently than classical computers.

04:55In 2020, a team of Chinese researchers claimed quantum advantage

04:59for a problem called boson sampling.

05:01They completed in 200 seconds a task

05:03that would take the world's fastest supercomputer 2.5 billion years.

05:07That's not just faster, it's entering a whole new realm of possibility.

05:10But it's not just about speed.

05:12Quantum computers excel at certain types of problems

05:15that classical computers struggle with.

05:17Take molecular simulation, for instance.

05:19In 2020, Google used a quantum computer

05:21to accurately simulate a chemical reaction for the first time.

05:24This could revolutionize drug discovery,

05:26potentially cutting development times from years to months.

05:29Financial institutions are getting in on the action too.

05:32JPMorgan Chase and Barclays have been experimenting with quantum algorithms

05:36for portfolio optimization and fraud detection.

05:38The potential for quantum advantage in finance is so great

05:41that Goldman Sachs predicts quantum computing

05:43could be a $29 billion industry by 2021.

05:46As more companies find quantum advantage in their fields,

05:49we're going to see a surge of investment in innovation.

05:52But hold on to your hats,

05:54because the next stage is where things really start to get wild.

05:57Stage six, quantum machine learning, the ultimate neural network.

06:01Imagine a neural network that doesn't just process information,

06:04but actually manipulates the fabric of reality to solve problems.

06:07That's the promise of quantum machine learning.

06:10Classical machine learning has already transformed our world

06:13from facial recognition to language translation.

06:16But quantum machine learning takes this to a whole new level.

06:19By leveraging quantum superposition and entanglement,

06:22quantum neural networks can explore vast solution spaces

06:25in ways that classical computers simply can't match.

06:28In 2021, researchers at the University of Science and Technology of China

06:33demonstrated a quantum machine learning algorithm

06:36that outperformed classical methods for a specific task.

06:39They used a 62-qubit quantum computer to solve a problem in 98 minutes

06:44that would take the fastest supercomputers eight years.

06:47But here's where it gets really interesting.

06:48Quantum machine learning isn't just faster.

06:51It can tackle problems that are practically impossible for classical systems.

06:55This could lead to breakthroughs in everything from climate modeling

06:58to discovering new materials.

06:59Tech giants are taking notice.

07:01Google has launched TensorFlow Quantum,

07:03a toolkit for building quantum machine learning models.

07:06IBM is integrating quantum circuits into its machine learning workflows.

07:09We're standing at the threshold of a new era in artificial intelligence.

07:13As we move to the next stage, remember this.

07:15Quantum machine learning isn't just an upgrade to our current AI systems.

07:19It's a fundamentally new approach

07:21that could redefine what's possible in computation and intelligence.

07:24Stage seven, quantum internet unhackable communication.

07:28Picture a world where information can be transmitted instantly

07:31across any distance with absolute security.

07:34That's the promise of the quantum internet.

07:36The key to this is a phenomenon called quantum entanglement.

07:39When particles are entangled,

07:40you can instantly know the state of one by measuring the other,

07:43no matter how far apart they are.

07:45Einstein called this spooky action at a distance,

07:48and it's the backbone of quantum communication.

07:50In 2017, Chinese scientists set a new record

07:53by demonstrating quantum entanglement

07:55over a distance of 1,200 kilometers using a satellite.

07:58This wasn't just a lab experiment.

08:00It was a proof of concept for a global quantum network.

08:03But why does this matter?

08:04Quantum communication is inherently secure.

08:06Any attempt to intercept or measure the quantum information destroys it,

08:10making it impossible to hack without detection.

08:13This could revolutionize fields like banking,

08:15government communications, and personal privacy.

08:18The race to build the quantum internet is already underway.

08:20The U.S. Department of Energy has unveiled a blueprint

08:23for a national quantum internet.

08:25The EU has launched a similar initiative,

08:27and China is already operating a 2,000-kilometer

08:30quantum communication line between Beijing and Shanghai.

08:33As we stand on the brink of this new era of communication,

08:36one thing is clear.

08:37The quantum internet isn't just an upgrade to our current networks.

08:40It's a fundamental reimagining

08:42of how information can be transmitted and secured.

08:45But even this isn't the final stage.

08:47What comes next will challenge our very understanding of reality itself.

08:51Stage 8, quantum simulation, redesigning reality.

08:54We've reached the final frontier of quantum computing,

08:57and it's mind-bending.

08:58Quantum simulation isn't just about crunching numbers faster.

09:01It's about creating virtual quantum realities

09:04that we can manipulate and study.

09:05Imagine being able to simulate the exact behavior

09:08of every atom in a complex molecule,

09:10or modeling the quantum effects in a superconductor.

09:13These tasks are practically impossible for classical computers,

09:16but they're right in the wheelhouse of quantum simulators.

09:19In 2019, Google's quantum computer simulated a simple chemical reaction.

09:24This might not sound impressive, but it's a huge step.

09:26As quantum simulators grow more powerful,

09:29we'll be able to design new materials atom by atom,

09:31revolutionizing fields like renewable energy and medicine.

09:35But it doesn't stop there.

09:36Some physicists believe that our universe itself

09:38might be a kind of quantum simulation.

09:40If that's true, then quantum simulators could give us a window

09:43into the very nature of reality.

09:44Companies are already jumping on board.

09:47IBM has partnered with ExxonMobil

09:49to explore quantum computing for energy applications.

09:52Volkswagen is using quantum simulation to optimize traffic flow in cities.

09:56As we push the boundaries of quantum simulation,

09:59we're not just solving problems,

10:00we're gaining the power to reshape reality itself.

10:03The implications are both thrilling and terrifying.
