| 摘 要： | 利用数值计算的方法，研究了Kerr介质腔中的J-C模型二能级原子和单模光场作用过程中信息熵和纠缠演化，得到了Kerr效应对纠缠态纠缠性质的影响。结果表明，Kerr介质对耦合体系的纠缠度有强烈的影响，在合适的Kerr效应下，量子态将长时间保持最大纠缠。

| Abstract: | Using the numerical method, the information entropy and evolution of entanglement of atom and a single mode light field of J-C model in the Kerr medium cavity have been studied. The effect of Kerr on the properties of entangled states has been obtained. The results show that Kerr medium has a strong influence on entanglement property of coupled system. With the appropriate Kerr effect, the maximally entangled quantum state will long remain. |

| Keywords: | quantum optics degree of entanglement Kerr medium information entropy |
