论文摘要
量子纠缠在量子信息处理中起着至关重要的作用。一夫一妻制和一夫多妻制的关系表征了多部分系统中的纠缠分布。我们提出了一类与基于rényi-$ a $熵的纠缠措施的$μ$ the功率相关的一夫一妻制的不平等，以及根据$μ$ th的rényii-$ $α$纠缠援助的$μ$ th。这些一夫一妻制和一夫多妻制的关系比现有关系更紧密。
Quantum entanglement plays essential roles in quantum information processing. The monogamy and polygamy relations characterize the entanglement distributions in the multipartite systems. We present a class of monogamy inequalities related to the $μ$th power of the entanglement measure based on Rényi-$α$ entropy, as well as polygamy relations in terms of the $μ$th powered of Rényi-$α$ entanglement of assistance. These monogamy and polygamy relations are shown to be tighter than the existing ones.
