摘　　要：制备GHZ态和cluster态是当前量子通讯及量子信息处理过程中一项重要课题,文章基于偏振光被囚禁原子光腔反射后所获得的法拉第旋转制备了子GHZ态和cluster态。该方案不需要腔场的强耦合条件,在低品质光腔中也能实现,从而大大降低了实验难度。Preparation of GHZ state and cluster state is an important subject in current quantum communication and quantum information processing.In this paper,the phonton GHZ state and cluster state are generated through the Faraday rotation,which results from the polarization photon being reflected by optical cavity with trapped atom.In this scheme,the strong-coupling condition is not needed and the analyzers can be generated in low-Q cavity,which further lowers the difficulty of the experiment.

关 键 词：GHZ态 cluster态 法拉第旋转 低品质腔
