双模真空压缩态在相阻尼情况下的量子纠缠与非定域性
Quantum nonlocality and entanglement for a two-mode squeezed vacuum state in a phase damping channel
摘要
Abstract
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.关键词
