摘要/Abstract

摘要： 纠缠单配性是量子纠缠中重要的物理性质之一, 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, 其平方满足单配性关系。Yuan 等提出了基于非广延熵纠缠平方服从的 μ 阶新型单配性关系, 其中阶数μ ≥ 2。这里给出一种更加严格的基于非广延熵纠缠平方的单配性关系。

Abstract: 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 measure and the squared Tsallis-q entropy entanglement obeys a monogamy relation. The entanglement monogamy relation satisfied by the μ-th power of squared Tsallis-q entropy entanglement for μ ≥ 2 has been proved by Yuan et al, and a new monogamy relationship for squared Tsallis-q entropy entanglement is presented here, which is tighter than that have been proven previously.

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