摘　　要：利用全量子理论研究了在二项式光场中介质和失谐量对级联三能级原子纠缠量的影响,结果显示:光场的强弱不同时,介质系数和失谐量对场熵的影响不同,在不同的光场中,选择合适的参数可得到稳定的纠缠态。In this paper,the influences of kerr medium coefficient and detuning on the entanglement evolution of cascade three-level atom in binomial light filed are studied based on quantum theory. The results show that the influences of kerr medium coefficient and detuning on the entanglement evolution are different with intensity of light field. Stable entanglement condition can be obtained by choosing an appropriate Kerr medium coefficient.
