摘　　要：提出一种利用经典场驱动单个二能级原子与 3个单模腔场发生色散相互作用 ,最后对原子进行选择性测量 ,从而实现类自旋的腔场GHZ态的制备。利用现有的腔QED技术 ,加上对原子的激光操纵—Stark效应和Rabi频率的交替控制 。A scheme is presented to generate the GHZ state of cavity-field with the dispersive interactions between a driven atom and three acvities,the GHZ state can be obtained by state-selective measurement on the atom.By using present cavity QED technology and laser manipulating the atom including stark Effect and Rabi flip controls,we can realize this scheme in experiment.
