The revolution is here. In breakthrough after breakthrough pioneering physicists are unlocking
a new quantum universe which provides a better representation of reality than our everyday
experiences and common sense ever could. The birth of quantum computers - which like
Schrödinger's famous dead-and-alive cat rely on entities like electrons existing in a mixture
of states - is starting to turn the computing world on its head. In his fascinating study of
this cutting-edge technology (first published as Computing with Quantum Cats and now featuring
a new foreword) John Gribbin updates his previous views on the nature of quantum reality
arguing for a universe of many parallel worlds where 'everything is real'. Looking back to Alan
Turing's work on the Enigma machine and the first electronic computer Gribbin explains how
quantum theory developed to make quantum computers work in practice as well as in principle. He
takes us beyond the arena of theoretical physics to explore their practical applications - from
machines which learn through 'intuition' and trial and error to unhackable laptops and
smartphones. And he investigates the potential for this extraordinary science to allow
communication faster than light and even teleportation as we step into a world of infinite
possibility.
