摘要
利用全量子理论讨论了kerr介质对级联三能级原子纠缠量的影响。通过对体系量子约化熵的计算,结果显示:耦合强度对体系的纠缠量影响不大;适当的选择kerr介质的系数,可获得稳定的纠缠态。
The influences of Kerr medium on entanglement quantity of three-level cascade atom are analyzed and discussed by using entire quantum theory. From the computation of system quantum reduction entropy, it is shown that the influence of coupling intensity on system＇s entanglement quantity is not evident and stable entanglement condition can be obtained by choosing an appropriate Kerr medium coefficient.
