摘要
提出一个基于腔QED系统实现量子相位门的设计方案.结果表明:在两个全同的二能级原子与光场相互作用过程中,借助经典场对原子实施Rabi翻转,控制原子射入腔场的速度v,选择原子与场相互作用参数l0,n和κ,可实现量子相位门.
A designed scheme has been proposed for the realization of quantum-phase gate based on the cav-ity QED .The results indicated that ,by means of classical fields to perform the Rabi rotations on the at-oms ,controlling the velocity of atom injecting ,and choosing the parameter and of interaction between the atoms and the light field ,quantum-phase gate can be achieved in the process of interaction between the light field and double identical two-level atoms .
