Bounds for multipartite concurrence
Ming Li, Shao-Ming Fei and Zhi-Xi Wang
Abstract
We study the entanglement of a multipartite quantum state. An inequality between the bipartite concurrence and the multipartite concurrence is obtained. More effective lower and upper bounds of the multipartite concurrence are obtained. By using the lower bound, the entanglement of more multipartite states are detected.
