From Colossus to Qubits
Pioneering study of the science behind quantum computing and what the new quantum reality will mean for mankind
Experimental and theoretical physicists are currently on the brink of developing computers operating on quantum principles. Quantum computation is one of the hottest scientific topics of the decade, and it depends on manipulating quantum entities – electrons, photons or single atoms – that are in two states at the same time. This breakthrough will turn the computing world upside down – the quantum computer represents an advance as far beyond the conventional computers we use in our daily lives as these devices are beyond the abacus.
Using scientific paradigms such as Schrödinger’s famous ‘dead and alive’ cat to explain the mechanics of how quantum computers work, John Gribbin explains the extraordinary implications of these machines, taking us beyond the world of physics to their practical applications in the military and big business. In this fascinating new quantum reality, communication can occur faster than light, computers will crack codes that are currently literally uncrackable and even teleportation is possible.
“Immensely readable... John Gribbin deftly traverses the peek-a-boo world of electrons and discombobulating possibilities of parallel universes to shed some much-needed light on the imminent technological revolution.”
“With a readable history of [quantum] theory, and of computers, Gribbin has penned a fascinating, pleasantly mind-boggling and probably quite essential book for non-eggheads.”
