Quantum Computing

Preface

Richard Feynman, a Nobel Laureate, first postulated^[1] a computer rooted in the laws of quantum mechanics that govern the behavior of subatomic particles such as muons, gluons, quarks, and bosons. It’s a theory that strains credulity at every turn—its bizarre concepts jar against everyday experience. A long line of distinguished quantum physicists from Niels Bohr to Albert Einstein and Richard Feynman have been exasperated by the very theory they helped create. Yet, surprisingly, the theory has correctly predicted every phenomenon that physicists have thrown at it. These same principles now have their sights trained on digital computing. For the first time since Eniac, the modern computer built at the University of Pennsylvania in 1946, ...
