| 摘 要： | 基于偏振光被囚禁原子光腔反射后所获得的法拉第旋转构造了光子Bell态分析器和GHZ态分析器,并能实现非破坏地识别所有的光子Bell态和GHZ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.

| Abstract: | The schemes are presented for realizing optical Bell-state and GHZ-state analyzers through the Faraday rotation, which results from polarization photon reflected by optical cavity with trapped atom. They can be extended to the case of completely distinguishing photon Bell-state and GHZ-state without destroying quantum qubit. In the schemes, strong-coupling condition is not needed and the analyzers can be implemented in low-Q cavity, which further lower the diffculty in experiment. |
