论文摘要
在各个子系统之间共享其属性时，多方系统的量子纠缠具有独特的功能。这被称为纠缠一夫一妻制。三方系统的传统一夫一妻制以总和证明。最近，发现同意也尊重产品形式的一夫一妻制。在这里，我们证明了纯三方系统并发的产品形式的紧密一夫一妻制关系。我们用几个示例说明了我们的关系，包括规范的三个Qubit状态，其中这种一夫一妻制关系饱和。
Quantum entanglement for multiparty system has a unique feature when it comes to sharing its property among various subsystems. This is famously stated as the monogamy of entanglement. The traditional monogamy of concurrence for tripartite system was proved in a sum form. Recently, it was found that concurrence also respects a monogamy in the product form. Here, we prove a tight monogamy relation in the product form for the concurrence of pure tripartite systems. We illustrate our relation with several examples, including the canonical three qubit states, where this monogamy relation is saturated.
