摘要/Abstract

摘要： 在微腔中通过Raman作用, 在原子系统中实现了三比特量子交换门.方案中由于原子与腔之间没有量子信息的交换, 可以忽略腔衰减的影响.这极大地提高了该方案在实验中实现的可能性.

Abstract: With Raman effect in micro cavity,to implement the three-qubit swap gate in atom system.In the scheme,there is no quantum information exchange between atom and cavity,it can ignore the influence of cavity decay.This markedly improves the probability of the scheme realization in experiment.

Key words: swap gate, atom, microcavity
