摘要
采用全量子理论方法,研究了初始在EPR纠缠态的两对两能级原子与两真空腔场的相互作用。结果表明:4原子与2真空腔系统的演化一般呈现纠缠现象,通过引入第5个原子的参与作用并对其进行选态测量,使得两EPR对的4个原子间处于退纠缠状态。
The system of two pairs of two-level atoms initially in the Einstein-Podolsky-Rosen(EPR) entangled states interacting with two cavities in vacuum fields was studied by means of the quantum theory.It has been shown that the evolution of the whole four-atom system generally exhibits entanglement,by introducing and measuring the fifth atom,a disentanglement scheme of one-off on this four-atom system is proposed.
