论文摘要
在本文中，我们研究了量子相关度量的动力学，例如纠缠和测量引起的非局部性（min）。从马尔可夫局部噪声下的任意钟形钟形混合状态开始，例如比特相位翻转，去极化和广义振幅阻尼通道，我们提供了通过一致和量子相关捕获的纠缠的衰变，这些纠缠和通过不同形式的最小形式（痕量距离，希尔伯特 - schmidt norm and norm and norm and etpropy and Tormpopy and Torgopy）捕获的量子相关性。观察到局部噪声对量子相关性动态行为的影响。我们显示了最小特定和重要特征的存在，例如复兴，噪声鲁棒性和相对于脱谐参数的突然变化。据观察，所有噪音都会导致部分纠缠状态截然纠缠。此外，我们显示了可分离量子状态的存在，其量子状态具有非零量子相关性。
In this article, we study the dynamics of quantum correlation measures such as entanglement and measurement-induced nonlocality (MIN). Starting from an arbitrary Bell diagonal mixed states under Markovian local noise such as bit-phase flip, depolarizing and generalized amplitude damping channel, we provide the decays of the entanglement measured by concurrence and quantum correlation captured by different forms of MIN (trace distance, Hilbert-Schmidt norm and relative entropy) as a function of the decoherence parameters. The effect of local noises on the dynamical behaviors of quantum correlation is observed. We show the existence of specific and important features of MIN such as revival, noise robustness and sudden change with respect to decoherence parameter. It is observed that all the noises cause sudden death of entanglement for partially entangled states. Further, we show the existence of separable quantum states with non-zero quantum correlations in terms of MIN.
