| 摘 要： | 基于A型三能级原子与腔场及经典场的相互作用理论，利用单光子探测器对从光腔中泄漏出来的光子进行符合测量，提出了一个四原子纠缠态的制备方案，四个分别处于不同光腔中的原子将以一定的概率处于GHZ态。

| Abstract: | Preparation scheme for four—atomic entangled state via cavity decay is presented by interaction between A—atoms and cavity modes.When two single—photon detectors only detect two photons,which leaked out from the four cavities simultaneously respectively,four distant atoms will be created into a four—atom GHZ entangled state with a certain probability. |
