The best computer in all possible worlds.(mathematician David Deutsch wants to build a quantum computer based on the many-universe theory)

From: Discover | Date: October 1, 1995| Author: | Copyright information

Deutsch believes that quantum mechanics can be put to advantage as computer components shrink to atomic size. He claims an ultimate quantum computer can be built which, by following an algorithm written by Peter Schor, solve any computational problem by calculating in many parallel universes at once.

DAVID DEUTSCH PREFERS NOT TO TRAVEL. HE would rather remain in his study, working. And after listening to the 42-year-old Oxford physicist for a moment, you understand his predilection. How horizons-expanding could any trip be to a man who believes that untold numbers of universes coexist ...
