研究了一般三重纠缠态的非马尔可夫动力学对Bell不等式破坏的影响。我们的研究结果表明,贝尔破坏的动力学不仅取决于系统与环境之间的耦合强度,但也对旋转角度。在强耦合和弱耦合情况下,当旋转角取一定值时,Bell非定域性可以通过环境在有限时间内诱导的退相干来消除。
The effect of the non-Markovian dynamics on the violation of Bell inequalities for a generic tripartite entangled state has been investigated. Our results imply that the dynamics of Bell violation depends not only on the coupling strengths between the system and the environment but also on the rotation angles. Under both the strong and weak couplings, the Bell nonlocality can be eliminated by the decoherence induced by the environment in finite time when the rotation angles take certain values.
