ClassX Video Lessons Youtube Channel Science Time Michio Kaku – This is Why Quantum Computers Will Change Everything – Part 2
Have you ever wondered how we might unlock the secrets of the universe? Enter the fascinating world of quantum computing, where tiny particles wield immense power. In this realm, traditional bits evolve into qubits, allowing data to exist not just as zeros or ones, but as both simultaneously. Imagine solving complex problems that would take classical computers billions of years in just a fraction of a second. Picture simulating every particle in a drug to revolutionize medicine or cracking codes once thought unbreakable. While it may sound like science fiction, quantum computers are indeed real.
Quantum computers are not just a concept from science fiction; they exist today. These machines might look like chandeliers due to their cooling pipes, but they are far more than decorative. The actual computing happens on a component about the size of a quarter, while the rest of the assembly, roughly the size of a suitcase, is dedicated to cooling. This is crucial because even the slightest disturbance, like a sneeze in another room, can disrupt calculations. Such sensitivity is one reason why quantum computing isn’t yet ready for widespread use.
About two to three years ago, two groups achieved what is known as quantum supremacy, where a quantum computer surpasses the capabilities of a digital computer. This milestone was reached by a team in China and another at Google. While quantum supremacy has been achieved for specific calculations, a fully programmable quantum computer is still in development. Major players like Google, IBM, and other Silicon Valley giants are racing to make this a reality, recognizing it as the next technological frontier.
Traditional computers use bits, which can be either a zero or a one. In contrast, quantum computers use qubits, which can be both zero and one simultaneously due to a phenomenon called superposition. Additionally, qubits can be entangled, meaning the state of one qubit can instantly affect another, regardless of distance. This allows quantum computers to solve problems like navigating a maze by exploring all paths at once, unlike traditional computers that try each path sequentially. Beyond speed, quantum computers can simulate nature at the atomic level, potentially leading to new materials and medical breakthroughs.
Building a practical quantum computer is incredibly challenging. These machines are extremely sensitive to their environment and must be isolated and cooled to near absolute zero. Despite these challenges, tech giants and startups are investing heavily in unlocking the full potential of quantum computing. As we stand on the brink of a quantum revolution, the question remains: who will lead this global race, and how will this technology reshape our world?
The Chinese have taken a unique approach by using light beams instead of electricity or electrons. By polarizing light beams, similar to how sunglasses work, they create optical transistors to build quantum computers. This method differs from the American approach, which uses a chandelier-like structure. The leaders in this race include China and American companies like Google, IBM, and Microsoft. The stakes are high, as the world economy, currently reliant on digital computers, could be transformed by quantum technology.
In the future, we may communicate with quantum computers through the cloud, requiring extensive cooling systems. Access could be as simple as using a digital interface on a wristwatch, earrings, or even contact lenses. Imagine contact lenses that allow you to access the internet by blinking, identify people, and translate languages in real-time.
Quantum computing promises not just to speed up processes but to revolutionize how we think, innovate, and interact with reality. The synergy between quantum computing and artificial intelligence could propel AI into new realms. Imagine AI systems that evolve, self-driving cars that adapt to drivers’ habits, or AI doctors that diagnose and design custom medical treatments instantly.
The pharmaceutical industry could be transformed as quantum computers simulate molecular interactions on an unprecedented scale, potentially leading to new drugs and treatments. On a larger scale, we could unravel the mysteries of the universe, gaining insights into phenomena like black holes and galaxy formation.
Economically, quantum computing could optimize global financial models, enhance supply chain efficiency, and solve complex logistical challenges that classical computers struggle with. In terms of security, the same technology that can crack today’s encryption can also create virtually unbreakable codes, leading to digital fortresses that evolve to defend themselves.
With these advancements come crucial ethical considerations. How do we ensure that the combination of AI and quantum computing is harnessed for the greater good? As we enter this new era, it’s not just the technology that needs to evolve, but our wisdom and foresight as well. We are like pioneers stepping onto an alien world, with knowledge as our compass.
Quantum computing invites us to reimagine innovation and problem-solving, challenging us to ask questions we never thought possible. As we delve into this new age, let us consider: are we ready to embrace the quantum revolution and the possibilities it holds? What will we create, and more importantly, who will we become?
The greatest consumer of quantum technology is nature itself. When you go outside, you see photosynthesis, trees, and the variations of life on Earth—all benefiting from quantum theory. Photosynthesis is a quantum process that takes light photons from the sun, combines them with carbon dioxide, and creates oxygen and sugars. This is why we can breathe and why humans can exist. We are beneficiaries of a quantum process that surpasses our most advanced chemistry. In other words, we must learn from nature.

Have you ever wondered how the mysteries of the universe could be unlocked? Enter the surreal realm of quantum computing. In this fascinating domain, tiny particles hold immense power. Here, bits evolve into qubits, and data is not just zeros or ones; it can be both at once. Imagine solving problems that would take classical computers billions of years in just a fraction of a second. What if we could simulate every single particle in a drug, revolutionizing medicine and saving countless lives, or crack codes that are deemed unbreakable? It might sound like technology from a science fiction movie, but quantum computers are very real.
These devices exist, and we’re not talking about science fiction. This is just one of several different kinds of quantum computers. Why does it look like a chandelier? Those are cooling pipes. The quantum computer computes on an object about the size of a quarter, while the whole assembly is about the size of a suitcase. Everything else consists of cooling pipes. Why? Because the slightest vibration—like someone sneezing in another room or a car backfiring—could upset the calculations. Errors can build up, which is one of the reasons why this technology is not yet ready for widespread use.
About two to three years ago, two groups achieved quantum supremacy. Quantum supremacy is the point at which a quantum computer exceeds the power of a digital computer. This milestone was reached by one group in China and another at Google. Quantum supremacy has been attained for certain discrete calculations. However, an all-purpose quantum computer that you can program does not yet exist, but there is a race among major players like Google, IBM, and others in Silicon Valley, all realizing that this is the next big thing.
So, what’s the significance of quantum computers? Traditional computers use bits as the basic unit of data, which can be either a zero or a one. In contrast, quantum computers use quantum bits, or qubits. Here’s where things get interesting: a qubit can be both a zero and a one at the same time, thanks to a quantum phenomenon called superposition. Now, add entanglement to the mix—another intriguing quantum trait. When qubits are entangled, the information in one instantaneously influences the other, regardless of the distance between them.
Imagine solving a maze: a traditional computer tries every path one after the other, while a quantum computer can explore all paths at once. It’s like having millions of well-coordinated copies of yourself working on the same problem. But it’s not just about speed; quantum computers could simulate nature at the atomic level. This means we could discover new materials or unlock the secrets of complex diseases, expediting the search for cures.
However, building a practical quantum computer is incredibly challenging. They are extremely sensitive to their environment and need to be isolated and cooled to near absolute zero. The race is on, with tech giants and startups pouring resources into harnessing the true power of quantum computing. As we stand on the brink of a quantum revolution, who will emerge victorious in this high-stakes global race? More importantly, how will this technology reshape our reality?
How did the Chinese achieve this? They did it not with electricity or electrons, but with light beams. Light beams can be polarized, similar to how sunglasses work. This polarization can be used to create an optical transistor, which can then be used to build a quantum computer. The Chinese quantum computer looks different from the American version, which resembles a chandelier. Instead, the Chinese version utilizes mirrors and beam splitters to control beams of light.
The leaders in this race include China, as well as American companies like Google, IBM, and Microsoft. What’s at stake? The world economy. Today, it depends on digital computers, which will eventually become obsolete. While we can’t say for sure when this will happen, Moore’s Law is beginning to flatten out. You can see this in the tech market; products are not becoming significantly more powerful year after year.
How will we communicate with a quantum computer? Likely through the cloud, which will require extensive cooling systems. You might access a quantum computer via a digital interface on a wristwatch, earrings, or even contact lenses. Imagine contact lenses that allow you to access the internet by blinking. These lenses could also identify people and translate languages in real-time.
As we explore the possibilities that quantum computing offers, this technology promises not just to speed things up but to revolutionize how we think, innovate, and interact with reality. The synergy between quantum computing and artificial intelligence could propel AI into realms we’ve only dreamed of. Imagine AI systems that evolve, self-driving cars that adapt to drivers’ habits, or AI doctors that can diagnose and design custom medical treatments instantly.
The pharmaceutical industry could be transformed, as quantum computers can simulate molecular interactions at an unprecedented scale, potentially leading to new drugs and treatments. On a larger scale, we could decipher the mysteries of the universe, understanding phenomena like black holes and the formation of galaxies.
Economically, quantum computing could optimize global financial models, enhance supply chain efficiency, and solve complex logistical challenges that classical computers struggle with.
