SpringerBriefs in Physics,2191-54233-030-42018-3 Includes bibliographical references and index.Introduction -- Brief history of quantum computing, starting with the invention of Shor's algorithm (1994) -- Introduction to quantum mechanics for pedestrians -- Electron spin as a qubit -- The main ideas and promises of quantum computing -- Current state of the art.This book addresses a broad community of physicists, engineers, computer scientists and industry professionals, as well as the general public, who are aware of the unprecedented media hype surrounding the supposedly imminent new era of quantum computing. The central argument of this book is that the feasibility of quantum computing in the physical world is extremely doubtful. The hypothetical quantum computer is not simply a quantum variant of the conventional digital computer, but rather a quantum extension of a classical analog computer operating with continuous parameters. In order to have a useful machine, the number of continuous parameters to control would have to be of such an astronomically large magnitude as to render the endeavor virtually infeasible. This viewpoint is based on the author’s expert understanding of the gargantuan challenges that would have to be overcome to ever make quantum computing a reality. Knowledge of secondary-school-level physics and math will be sufficient for understanding most of the text; the few paragraphs that are more technical are highlighted in italics.SpringerBriefs in Physics,2191-5423PhysicsQuantum computersSpintronicsQuantum physicsComputer sciencePopular Science in Physicshttps://scigraph.springernature.com/ontologies/product-market-codes/Q29000Quantum Information Technology, Spintronicshttps://scigraph.springernature.com/ontologies/product-market-codes/P31070Quantum Physicshttps://scigraph.springernature.com/ontologies/product-market-codes/P19080Quantum Computinghttps://scigraph.springernature.com/ontologies/product-market-codes/M14070Popular Computer Sciencehttps://scigraph.springernature.com/ontologies/product-market-codes/Q23000Physics.Quantum computers.Spintronics.Quantum physics.Computer science.Popular Science in Physics.Quantum Information Technology, Spintronics.Quantum Physics.Quantum Computing.Popular Computer Science.500Dyakonov Mikhail Iauthttp://id.loc.gov/vocabulary/relators/aut731343MiAaPQMiAaPQMiAaPQBOOK9910739408403321Will We Ever Have a Quantum Computer2087438UNINA
