我们研究了两个量子比特在一个公共结构库中的纠缠动力学。我们证明了对于某些类型的纠缠态，纠缠突然死亡发生，而对于某些初始因子化的状态，纠缠突然出生发生。非马尔可夫水库的反作用是负责复苏的纠缠突然死亡后发生，也为解开纠缠突然出生后的时期。
We study the exact entanglement dynamics of two qubits in a common structured reservoir. We demonstrate that for certain classes of entangled states, entanglement sudden death occurs, while for certain initially factorized states, entanglement sudden birth takes place. The backaction of the non-Markovian reservoir is responsible for revivals of entanglement after sudden death has occurred, and also for periods of disentanglement following entanglement sudden birth.
