The Power of Quantum Computing: Changing the World

Quantum computing is the next revolution that will change everything, including security and the economy. Michio Kaku explains the evolution of computing, leading to the development of quantum computers.

00:00:00 Quantum computing, the ultimate computer, is the next revolution that will change everything, including security and the economy.

💻 The arrival of quantum computers could be even more historic than the impact of digital computers.

🏃‍♂️ Major players are involved in a race to perfect quantum computers to prevent Silicon Valley from declining.

🔒 Quantum computers have the ability to crack any code based on digital technology, which concerns security agencies.

🌍 Quantum computers will bring significant changes to the economy, problem solving, and our interaction with the Universe.

00:01:42 Michio Kaku explains the evolution of computing, from analog to digital, leading to the development of quantum computing.

💡 The history of computing started with analog computers used to map the motion of celestial bodies.

🔧 Charles Babbage created the ultimate analog computer with hundreds of gears and levers, which was valuable for banking and commerce.

💻 The development of digital computers, led by Alan Turing, revolutionized computation and played a crucial role in World War II.

00:03:23 Michio Kaku discusses the next revolution in computing: quantum computers. Unlike traditional computers, quantum computers operate on atoms and particles, allowing for incredible computational power.

⚙️ The digital revolution is based on transistors and operates on zeros and ones at the speed of electricity.

📈 Quantum computers compute on atoms rather than on transistors and have much higher computational power due to electrons being able to be in two places at the same time.

📣 Quantum computers require a new set of mathematics to discuss the waves that make up a molecule.

00:05:10 Quantum mechanics can be reduced down to a cat, Schrodinger's cat. Until you open the box, the cat can exist in both dead and alive states simultaneously. Quantum computers compute on parallel universes, making them powerful.

🔑 Quantum mechanics can be reduced down to Schrödinger's cat, which exists in a superposition of two states.

🔑 Quantum computers compute on parallel universes, giving them immense power.

🔑 A quantum computer is significantly faster than a digital computer.

00:06:50 Quantum computing has the potential to surpass the power of ordinary digital computers by using qubits instead of bits. The biggest challenge is 'decoherence', which causes vibrations at different frequencies.

🔮 Quantum computers use qubits to represent all possibilities between spin up and spin down.

🔩 The latest generation of quantum computers can model thousands of qubits, with the goal of reaching a million.

💻 Quantum computers aim to exceed the power of ordinary digital computers but are hindered by the problem of decoherence.

00:08:30 Quantum computing has hurdles to overcome, but the benefits are immense. It can revolutionize food supply, energy, and medicine.

🌍 Nature is better than us at creating coherence in quantum processes.

💻 There are hurdles in quantum computing, but the benefits are immense.

🌱 Quantum computers can help with food supply, energy, and medicine.

00:10:10 Quantum computing enables modeling diseases at the molecular level and solving complex equations to understand the Universe.

💡 Quantum computers have the potential to model and cure currently incurable diseases at a molecular level.

🔁 Quantum computers could revolutionize medicine by turning traditional approaches upside down.

🌌 Quantum computers may be able to solve the complex equations that have so far eluded scientists, such as those related to the theory of the entire Universe.
