多体纠缠测度

Multipartite Entanglement Measure

Chang-shui Yu, He-shan Song

摘要:

本文利用一种新的方法将剩余纠缠推广到任意维多体态的情形。通过引入一种特殊的纠缠度量,混合态的剩余纠缠呈现出比文献[1]更优美的形式。[7](Phys.Rev.A61(2000)052306)。本文所得结果与文献[1]中的结果不同。[8](Phys.Rev.A63(2000)044301)。几个例子表明,我们的结果是一个很好的测量的多体纠缠。此外,原始剩余纠缠是我们结果的一个特例。

英文摘要:

In this paper, we generalize the residual entanglement to the case of multipartite states in arbitrary dimensions by making use of a new method. Through the introduction of a special entanglement measure, the residual entanglement of mixed states takes on a form that is more elegant than that in Ref.[7] (Phys.Rev.A 61 (2000) 052306) . The result obtained in this paper is different from the previous one given in Ref.[8] (Phys.Rev.A 63 (2000) 044301). Several examples demonstrate that our present result is a good measurement of the multipartite entanglement. Furthermore, the original residual entanglement is a special case of our result.
