Quantum computing explained

You've probably heard of quantum computing, but like most of us you probably don't have the slightest idea what it is. The famous physicist Niels Bohr once said, "If anybody says he can think about quantum physics without getting giddy, that only shows he has not understood the first thing about them." Radio New Zealand interviewed science writer John Gribbin who did an excellent job explaining what quantum computing is and how it may change computation for ever. Gribbin's new book Computing with Quantum Cats: From Colossus to Qubits looks like a great read.
