Precise detection of multipartite entanglement in four-qubit Greenberger--Horne--Zeilinger diagonal states
Xiao-yu Chen, Li-zhen Jiang, Zhu-an Xu
We propose a method of constructing the separability criteria for multipartite quantum states on the basis of entanglement witnesses. The entanglement witnesses are obtained by fin…

Matched witness for multipartite entanglement
Xiao-yu Chen, Zhu-an Xu
We transform the way of finding entanglement criterion into two steps: to obtain necessary criterion of separability by maximizing an algebra function for a set of characteristic v…

Necessary and sufficient criterion for k-separability of N-qubit noisy GHZ states
Xiao-yu Chen, Li-zhen Jiang, Zhu-an Xu
A Multipartite entangled state has many different kinds of entanglement specified by the number of partitions. The most essential example of multipartite entanglement is the entang…
