量子关联简介

Introduction to quantum correlations

  • 摘要: 量子纠缠作为一种非局域的关联,是一种重要的资源而被广泛应用于量子信息处理。然而,最近的研究结果发现,可分态中也可以存在非经典的关联,量子纠缠只是量子关联的一部分;非纠缠的量子关联在一些量子通信和量子计算任务中扮演着重要的角色。文章简要综述了量子关联的基本概念,描述了几种常见的量子关联度量,并介绍了量子关联在量子信息处理中的作用以及一些最新动态。

     

    Abstract: Quantum entanglement is a kind of nonlocal quantum correlations that has been widely used in quantum information processing. Recent studies have found that quantum (non-classical) correlations can exist even in separable states, and quantum entanglement is just one form of quantum correlation. Non-entangled quantum correlations play important roles in various quantum communications and quantum computing tasks. In this article, we briefly review the basic concepts of quantum correlation, introduce some commonly used measures of quantum correlation, and describe various applications and recent developments, together with several important references.
