GHZ和三原子W态的稳健制备

Robust Preparation of GHZ and W States of Three Distant Atoms

Chang-shui Yu, X. X. Yi, He-shan Song, D. Mei

摘要:

本文提出了一种产生三个远距离原子的Greenberger-Horne-Zeilinger(GHZ)态和W态的方案。该方案利用了光学腔中原子发射的不可分辨光子的量子统计效应。该方案的优点是它们对检测效率低和光子的异步发射的鲁棒性。此外,在Lamb-Dicke极限下,该方案不需要探测器的同时点击,这使得该方案在实验中更容易实现。

英文摘要:

Schemes to generate Greenberger-Horne-Zeilinger(GHZ) and W states of three distant atoms are proposed in this paper. The schemes use the effects of quantum statistics of indistinguishable photons emitted by the atoms inside optical cavities. The advantages of the schemes are their robustness against detection inefficiency and asynchronous emission of the photons. Moreover, in Lamb-Dicke limit, the schemes do not require simultaneous click of the detectors, this makes the schemes more realizable in experiments.
