研究了双模真空压缩态在相阻尼情况下的非定域动力学和纠缠特性.在得出该系统密度演化算符的明晰表达式后,我们基于"宇旋算符"而引入合适的Bell算符,从而很好的揭示了该态的非定域性.通过计算其相对熵纠缠度,我们也很好的揭示出其纠缠特性.

We study dynamics of quantum nonlocality and entanglement for a two-mode squeezed vacuum state in a phase damping channel. After getting the explicit expression of the density evolution operator of the system, we uncover the nonlocality of the state by introducing appropriate also clear from the calculation of relative entropy of entanglement.
