Abstract

We study the detection of multipartite entanglement based on the generalized local uncertainty relations. A sufficient criterion for the entanglement of four-partite quantum systems is presented in terms of the local uncertainty relations. Detailed examples are given to illustrate the advantages of our criterion. The approach is generalized to general multipartite entanglement cases.

摘要

我们研究基于广义局部不确定性关系的多体纠缠检测。根据局部不确定性关系给出了四体量子系统纠缠的一个充分判据。给出了详细的例子来说明我们判据的优势。该方法被推广到一般的多体纠缠情形。
