制备n原子GHZ类态

我们提出一个方案通过极化光子的干涉来制备囚禁在相距很远的腔中的n原子GHZ类态。在该方案中，原子腔耦合强度小于腔衰减率。因此对腔的品质因子的要求大大降低了，而且，该方案的保真度不受探测器效率和原子自发衰变的影响。 中文关键词：纠缠制备；GHZ类态；腔QED

Generation of Greenberger-Horne-Zeilinger-type

We propose a scheme for generating Greenberger-Horne-Zeilinger-type states of n atoms trapped in the distant cavities by using interference of polarized photons.In our scheme, the atom-cavity coupling strength is smaller than the cavity decay rate.Thus,the requirement on the quality factor of the cavities is greatly relaxed.Furthermore,the fidelity of our scheme is not affected by the detection inefficiency and atomic decay
