Michio Kaku: How quantum computers compute in multiple universes at once
"- The next revolution will be quantum computers that will make the digital computer look like an abacus. In other words, the future of digital computers is to wind up in the garbage can. We're talking about a new generation of computers, the ultimate computer, a computer that computes on atoms, the ultimate constituents of matter itself. Quantum computers have the capability of changing every aspect of our life. The economy, health, transportation, everything could be changed by quantum computers."
"Take a look, for example, of food supply. We rely upon fertilizers. There was a green revolution that took place that allows us to feed the population of the world. But that green revolution is slowly coming to an end. We need a second green revolution, being able to take nitrogen from the air and combine it to make ammonia and fertilizer. And already we're trying to use quantum computers to unlock the secret of how to make fertilizer from nitrogen."
Quantum computers represent a new generation of machines that compute on atoms and exploit quantum effects to solve problems intractable for digital computers. They will outperform classical computers by handling exponentially large problem spaces, enabling breakthroughs across economy, health, transportation, agriculture, and energy. Quantum simulation can reveal chemical pathways for nitrogen fixation to produce fertilizers, potentially enabling a second green revolution. Quantum algorithms may stabilize fusion plasmas and optimize fusion reactors to deliver abundant, low-waste energy from seawater. Quantum computing can also accelerate drug discovery by simulating molecular interactions rather than relying on slow trial-and-error laboratory testing.
