摘要
我们研究了三方和多方量子系统中的一夫多妻特性。在三方系统中,我们建立了三方系统中一夫多妻制的解集,并找到了量子相关Q的连续度量为一夫多妻制的充分必要条件。在多比特系统中,我们提供了 n 量子比特系统中具有 \(n\ge 4\) 的一夫多妻制的广义定义,然后,我们建立了具有一夫多妻制幂 \(\beta \) 的一夫多妻制不等式。接下来,我们还将描述,根据我们在多比特系统中的新定义,任何辅助纠缠都可以是一夫多妻制。为了更好地理解,我们用直角三角形和四面体来解释我们新的一夫多妻关系。此外,我们还研究了单个量子比特与其剩余伙伴之间的一夫多妻关系,以丰富我们的研究成果。
Polygamy relations for tripartite and multipartite quantum systems
We study the polygamy property in tripartite and multipartite quantum systems. In tripartite system, we build a solution set for polygamy in tripartite system and find a sufficient and necessary condition of the set for continuous measure of quantum correlation Q to be polygamous. In multipartite system, we provide generalized definitions for polygamy in n-qubit systems with \(n\ge 4\), and then, we build polygamy inequalities with a polygamy power \(\beta \). Next we also describe that any entanglement of assistance can be polygamy according to our new definition in multipartite systems. For better understanding, we use right triangle and tetrahedron to explain our new polygamy relations. Moreover, the polygamy relations between each single qubit and its remaining partners are also investigated to enrich our results.
