Quantum Computing from Colossus to Qubits

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\'.
