标题： Two-qubit entanglement dynamics for two different non-Markovian environments

摘要： 我们研究了两个非相互作用量子比特分别浸没在各自环境中的纠缠时间演化行为，涉及两种非马尔可夫条件：一个高$Q$腔体，略微偏离量子比特跃迁频率共振，并且具有非理想的光子带隙。 我们发现，通过调节腔体-量子比特失谐，可以在第一种情况下发生纠缠损失的回复和延迟；而在非理想光子带隙中，则会发生部分纠缠陷阱现象。 显示英文摘要

摘要： We study the time behavior of entanglement between two noninteracting qubits each immersed in its own environment for two different non-Markovian conditions: a high-$Q$ cavity slightly off-resonant with the qubit transition frequency and a nonperfect photonic band-gap, respectively. We find that revivals and retardation of entanglement loss may occur by adjusting the cavity-qubit detuning, in the first case, while partial entanglement trapping occurs in non-ideal photonic-band gap.
