利用辅助单边腔分别捕获碱金属原子，提出了双光子Bell态和三光子Greenberger-Horne-Zeilinger（GHZ）态的分析器方案.此外，所有的双光子Bell态和三光子GHZ态都可以被非破坏性地区分。讨论了原子自发辐射和输出耦合效率的影响。
With the ancillary one-sided cavities each trapping an alkali atom, the schemes for the analyzers of two-photon Bell states and three-photon Greenberger–Horne–Zeilinger (GHZ) states are proposed, respectively. Moreover, all of two-photon Bell states and three-photon GHZ states can be nondestructively distinguished. The influence of atomic spontaneous emission and output coupling inefficiency are discussed.
