Bounds on Multipartite Concurrence and Tangle

Jing Wang, Ming Li, Hongfang Li, Shao-Ming Fei and Xianqing Li-Jost

Abstract

We present an analytical lower bound of multipartite concurrence based on the generalized Bloch representation of density matrices. It is shown that the lower bound can be used as an effective entanglement witness of genuine multipartite entanglement. Tight lower and upper bounds for multipartite tangles are also derived.
