Quantum Supremacy

About the book

In Quantum Supremacy, Michio Kaku takes us to the threshold of a new era: the moment when the old empire of silicon begins to yield to machines capable of using atoms themselves as instruments of calculation. The quantum computer appears here not as a simple evolution of the digital computer, but as a profound break — a technology capable of exploiting superposition, entanglement and quantum probabilities to solve problems that classical supercomputers could never tackle within a useful timescale.

The journey begins with the end of Moore’s Law and the crisis of traditional computing, passes through Turing, Feynman, Schrödinger, Everett and many worlds, and advances towards the technological race between companies, governments and laboratories seeking to master civilisation’s next great leap. At its centre lies a decisive question: will whoever controls quantum computing also control an essential part of the future?

But Kaku goes beyond the machine. He shows how this new power could transform medicine, decipher proteins, accelerate drug discovery, combat incurable diseases, create better batteries, revolutionise agriculture, simulate the climate, bring nuclear fusion closer and open new windows onto the Universe itself. Quantum computing thus appears as a key to the most intimate layers of matter, life and energy.

Quantum Supremacy tells the story of a frontier catching fire: the transition from binary calculation to a technological intelligence capable of thinking with Nature’s deep rules. A book about computers, certainly — but above all about the possibility of humanity finally learning to simulate reality from its most fundamental level.
