Abstract

A universal characterization of non-Markovianity for any open hybrid quantum systems is presented. This formulation is based on the negativity volume of the generalized Wigner function, which serves as an indicator of the quantum correlations in any composite quantum systems. It is shown, that the proposed measure can be utilized for any single or multi-partite quantum system, containing any discrete or continuous variables. To demonstrate its power in revealing non-Markovianity in such quantum systems, we additionally consider a few illustrative examples.

摘要

给出了任意开放混合量子系统非马尔可夫性的通用表征。该表述基于广义维格纳函数的负体积，它可作为任意复合量子系统中量子关联的一个指标。结果表明，所提出的度量可用于包含任意离散或连续变量的任何单部分或多部分量子系统。为了证明其在揭示此类量子系统非马尔可夫性方面的能力，我们还考虑了一些示例。
