| 摘 要： | 文章选取J-C模型,在此模型下引入双腔双原子体系。考虑这两个原子的纠缠问题,通过泰勒展开计算出此体系中的量子关联concurrence,并最终推导出关于concurrence的方程,这个方程很好地预测了自旋1/2量子纠缠的产生与坍塌。

| Abstract: | In this article we select the J-C model,then introduce the double-cavity and double-atom system in this model,and consider this two-atom entanglement,using the Taylor expansion to calculate the quantum correlations concurrence in this system and eventually deduce a equation about the concurrence,which predicts the sudden death and the rebirth of the spin quantum entanglement. |
