非马尔可夫环境下原子-原子纠缠中的量子Zeno和反Zeno效应

Quantum Zeno and anti-Zeno effect in atom-atom entanglement induced by non-Markovian environment

Yang Li, Hong Guo

摘要:

研究了两个二能级原子耦合到一个有耗腔中纠缠的动力学行为。我们发现,解纠缠的速度是一个减少(增加)的函数的阻尼率的腔/近(远)共振耦合。给出了这些现象的定量解释,并进一步指出它们与非马尔可夫环境诱导的量子Zeno和反Zeno效应有关。

英文摘要:

The dynamic behavior of the entanglement for two two-level atoms coupled to a common lossy cavity is studied. We find that the speed of disentanglement is a decreasing (increasing) function of the damping rate of the cavity for on/near (far-off) resonant couplings. The quantitative explanations for these phenomena are given, and further, it is shown that they are related to the quantum Zeno and anti-Zeno effect induced by the non-Markovian environment.
