一类量子比特-垂特态中测量诱导的非经典关联(英文)

Measure-induced non-classicality in a family of qubit-qutrit correlated states

采用文献[Luo S L.Using measurement-induced disturbance to characterize correlations as classical or quantum[J].Phys Rev A,2008,77:022301]中提出的测量诱导扰动方法计算了一类2体可分量子比特-垂特关联态中的非经典关联.具体来说,就是利用谱分解技巧来获得每个态中的经典关联,继而得出其中包含的量子关联.经过对这些态中的量子关联的详尽分析,一些独特的性质被展示出来.

Measure-induced non-classicality （MINC） in a family of bipartite separable qubit-qutrit correlated states was evaluated by using the MID method proposed by the reference [Luo S L.Using measurement-induced disturbance to characterize correlations as classical or quantum[J].Phys Rev A,2008,77：022301].Specifically,classical correlation in each state was derived via the spectrum resolution technique and then the MINC （i.e.,quantum correlation） was extracted.The MINC was amply analyzed so that some distinct features were exposed.
