摘要
提出了由相干耦合原子与单模相干腔场相互作用的物理模型。利用全量子理论,研究了该系统的演化过程,结果表明:在一定时间条件下量子原子纠缠态与光场纠缠态可以相互转换;还发现,适当控制原子与腔场相互作用的时间,原子纠缠态或光场纠缠态可以保持初态不变。
The physics system consisting of coherent coupled-atom interaction with coherent single-mode cavity-field is proposed. Using the complete quantum theory, the evolution process of the system is studied It is found that the quantum atom entangled states and light field entangled states can be transferred into each other under a certain temporal condition. Otherwise, the initial state of the atom or the light field entangled states can be completely preserved by controlling the time of the atoms interaction with the light fields .
