Abstract

In [S. L. Luo, Using measurement induced disturbance to characterize correlations as classical or quantum, Phys. Rev. A77 (2008) 022301], the author presented a statistical correlation measure for bipartite quantum states using measurement induced disturbance. In this paper, motivated by this correlation measure, we obtain some necessary conditions for [Formula: see text]-classical states in multipartite quantum systems, and obtain a relation between the set of [Formula: see text]-classical states and the set of [Formula: see text]-product states; Secondly, we introduce a class of correlation measures based on trace distance using measurement induced disturbance in order to quantify the strength of correlation for non-[Formula: see text]-classical states; Lastly, we introduce the concept of quantum channel with respect to [Formula: see text]-partition, it is simply denoted by identical-[Formula: see text]-channel, and furthermore discuss the influences of the correlation measure under identical-[Formula: see text]-channel.

用测量引起的扰动表征多部分非k-经典态的相关性

在[S.L.Lo，使用测量诱导的扰动将相关性表征为经典或量子，Phys.Rev.A77（2008）022301]中，作者提出了使用测量诱导扰动的二分量子态的统计相关性度量。本文在这个相关测度的激励下，得到了多部分量子系统中[公式：见正文]-经典态的一些必要条件，并得到了[公式：看正文]-古典态的集合与[公式：见正文]-乘积态的集合之间的关系；其次，我们引入了一类基于迹线距离的相关测度，利用测度引起的扰动来量化非[公式：见正文]经典状态的相关性强度；最后，我们引入了关于[公式：见文本]-划分的量子通道的概念，它简单地用相同的-[公式：见图文本]-通道表示，并进一步讨论了相同的-[公式：见正文]-通道下相关测度的影响。
