摘要
相干度量是描述量子相干性的重要数学工具,从不同的角度去研究不同的相干度量对研究量子相干性有很大的帮助.因此,以两量子比特纯态以及 2种特殊的Bell对角态(Werner态和MNMS态)为研究对象,对其在相对熵部分相干和斜信息部分相干上相干值的大小进行比较,可以发现相对熵部分相干和斜信息部分相干度量对于以上所提出的 3类特殊的两比特量子态都有相同的量子态序.
Abstract
Coherence measure is an important mathematical tool for describing quantum coherence.It is very helpful to study quantum coherence by investigating different coherence measures from the perspective of the ordering states.Therefore,the two-qubit pure state and two special Bell-diagonal states(Werner state and MNMS state)are taken as the research objects,and their coherence values on relative entropy partial coherence and skew information partial coherence are compared.It is found that the relative entropy partial coherence and the skew information partial coherence measure have the same quantum ordering state for the above three special two-qubit quantum states.
