摘要
Quantum computers can, in principle, exceed the speed of ordinary computers by taking advantage of quantum coherence and entanglement. It is possible to find a "needle in a haystack" of N-1 straws in only rootN searches by utilizing coherent superposition states. In the present paper we show how modem quantum optics may provide a simple and practicable quantum search procedure, which may also yield insights into quantum search algorithms in general.
