分布纠缠的一夫多妻

Polygamy of Distributed Entanglement

Francesco Buscemi, Gilad Gour, Jeong San Kim

摘要:

虽然量子纠缠被认为是一夫一妻制的(即共享纠缠在多体设置中受到限制),但在这里,我们表明分布式纠缠(或纠缠的潜力)本质上是一夫多妻制的。通过建立单向不可定域纠缠的概念并研究其性质,给出了任意维三重量子系统中分布式纠缠的一个多偶不等式.我们还提供了多量子比特系统中的一夫多妻不等式,以及UE和其他相关性度量之间的一些权衡。

英文摘要:

While quantum entanglement is known to be monogamous (i.e. shared entanglement is restricted in multi-partite settings), here we show that distributed entanglement (or the potential for entanglement) is by nature polygamous. By establishing the concept of one-way unlocalizable entanglement (UE) and investigating its properties, we provide a polygamy inequality of distributed entanglement in tripartite quantum systems of arbitrary dimension. We also provide a polygamy inequality in multi-qubit systems, and several trade offs between UE and other correlation measures.
