在腔场中两原子共生纠缠度的变化及最大纠缠态的制备

Evolution of Two Atoms' Concurrence and Preparation of an Entangled State Through Cavity

讨论了两原子与腔场共振相互作用时两原子共生纠缠度(Concurrence)随时间的演化规律.结果表明:通过控制原子和腔场相互作用时间,可制备两原子的最大纠缠态.另外,还考虑了原子自发辐射和腔场衰变对纠缠度的影响.

Discusses the evolution of two atoms＇ concurrence when two atoms and a cavity mode interact resonantly. The result shows that the maximally entangled state can be prepared by controlling interaction time. In addition, it also consider the influence of atomic spontaneous emission and cavity decay on atomic concurrence.
