The runaway success of the microchip processor may be nearing its end, with profound implications for our economy, society and way of life, even leaving Silicon Valley as a new Rust Belt, its technology obsolete. Step forward the quantum computer, which harnesses the power and complexity of the atomic realm, and may be useful in solving humanity's greatest challenges from climate change, to global starvation, to incurable diseases. Humanity's next great technological achievement already promises to be every bit as revolutionary as the transistor and microchip once were. Its unprecedented gains in computing power and unique ability to simulate the physical universe herald advances that could change every aspect of our lives. Corporations and whole nations are betting on quantum computing, hoping to exploit its power to design more efficient vehicles, create life-saving new drugs and streamline industries to revolutionize the economy. But this is only the beginning. Quantum computers could allow us to finally create nuclear fusion reactors that produce clean, renewable energy without radioactive waste or threats of meltdown. They could help us crack the biological processes that generate natural, cheap fertilizer and enable us to feed the world's growing populations. And they could unravel the fiendishly difficult protein folding that lies at the heart of previously incurable diseases such as Alzheimer's, motor neurone disease and Parkinson's, helping us to live longer, healthier lives. Told with Kaku's signature clarity and enthusiasm, Quantum Supremacy is the story of this exciting frontier and the race to claim humanity's future.
