论文摘要
我们从集合互补关系的角度研究了系统环境信息流。我们考虑一些常用的嘈杂量子通道：振幅阻尼，相阻尼，位翻转，比特相位翻转，相位翻转，去极化和相关降压阻尼。通过从纠缠的两分纯量子状态开始，线性伦理是纠缠的量化剂，我们研究了纠缠如何重新分布，并在整个系统的自由度之间进行一般性相关性。例如，可以根据系统不同分区的多部分量子相干性或相关量子相干性的多部分量子相干性或Interms表示纠缠熵。此外，我们注意到，对于去极化和比特相的翻转通道波和粒子方面candecrease或同时增加。此外，通过将环境视为纯量子系统的一部分，线性熵不仅是特定子系统混合性的量度，而且是子系统与世界其他地区的相关度量。
We investigate the system-environment information flow from the point of view ofcomplete complementarity relations. We consider some commonly used noisy quantum channels:Amplitude damping, phase damping, bit flip, bit-phase flip, phase flip, depolarizing, and correlatedamplitude damping. By starting with an entangled bipartite pure quantum state, with the linearentropy being the quantifier of entanglement, we study how entanglement is redistributed and turnedinto general correlations between the degrees of freedom of the whole system. For instance, it ispossible to express the entanglement entropy in terms of the multipartite quantum coherence or interms of the correlated quantum coherence of the different partitions of the system. In addition,we notice that for the depolarizing and bit-phase flip channels the wave and particle aspects candecrease or increase together. Besides, by considering the environment as part of a pure quantumsystem, the linear entropy is shown to be not just a measure of mixedness of a particular subsystem,but a correlation measure of the subsystem with rest of the world.
