摘要
分别利用度量纯态纠缠的两种常用方法-von Neumann熵和共生纠缠,探讨了单光子J-C模型中和双光子J-C模型中原子-腔场的纠缠随时间的演化,并得出了此纠缠随时间演化的规律.
we investigate the evolution of atom-cavity entanglement versus time in single-photon J-C model and twophoton J-C model by means of yon Neumann entropy and concurrence, respeetively; and at the same time, we find out the evolution law of entanglement versus time.
