The Zen of Quantum Computing

A computer that delivers an answer without being turned on. Don't ask me to explain it.

Update: John Derbyshire has the same difficulty. He points out that the idea of an on-off switch on a quantum computer is inconsistent with the concept. I suppose that the programming process must be more like defining the results you need and leaving it to the computer to collapse the wave on a solution that fits that definition, although I'm still guessing.
