A necessary and sufficient criterion for multipartite separable states
Shengjun Wu, Xuemei Chen, Yongde Zhang
We present a necessary and sufficient condition for the separability of multipartite quantum states, this criterion also tells us how to write a multipartite separable state as a c…

Multipartite pure-state entanglement and the generalized GHZ states
Shengjun Wu, Yongde Zhang
We show that not all 4-party pure states are GHZ reducible (i.e., can be generated reversibly from a combination of 2-, 3- and 4-party maximally entangled states by local quantum o…
