摘要: 纠缠单配性是量子纠缠中一类重要的物理性质,利用这一性质可以描述多体量子比特系统中的纠缠结构。非广延熵纠缠是一种很好的纠缠度量方式,当参数在 (5-131/2)/2≦q≦(5+131/2)/2 内,其平方满足单配性关系。基于前人的研究,提出了单参数 (5-131/2)/2≦q≦(5+131/2)/2 范围下基于非广延熵纠缠服从阶数μ≧2的新型单配性关系。该关系相比宋伟等提出的基于非广延熵纠缠平方的单配性关系更加严格。

Abstract:

The monogamy of entanglement is an important property in quantum entanglement,which can be used to characterize the entanglement structure in multipartite systems. Tsallis-q entropy entanglement is a well-known entanglement measures, and the squared Tsallis-q entropy entanglement obeys a monogamy relation with(5-131/2)/2≦q≦(5+131/2)/2 . A new entanglement monogamy relation is presented when the μ-th power of Tsallis-q entropy entanglement with(5-131/2)/2≦q≦(5+131/2)/2 is satisfied withμ≧2. It is shown that this monogamy relation is more strict than the monogamy relation of squared Tsallis-q entropy entanglement proposed by Song Wei et al.

Key words: quantum optics, entanglement, monogamy, Tsallis-q entropy entanglement
