摘要
本文通过对存在Kerr介质时J-C模型中的二能级原子和单模光场作用过程中纠缠态的研究,得到了Kerr介质对纠缠态纠缠性质的影响,发现Kerr介质对纠缠场的纠缠度有强烈的影响,在特定的Kerr效应下,量子态将长时间保持最大纠缠态,这一结果将有助于纠缠态的制备。
In this paper,through studying the interaction between a single mode emission field and a two-level atom in J-C Model with Kerr Medium,the entanglement amount of entanglement state is obtained.We find that Kerr medium exhibits strong influence on the amount of entanglement in this kind of J-C Model.When Kerr effect is at special value the quantum state will stay in the most entangled state for a long time.This will do some help to the preparation of entangled states.
