Entanglement detection beyond the cross-norm or realignment criterion
Cheng-Jie Zhang, Yong-Sheng Zhang, Shun Zhang +1
Separability problem, to decide whether a given state is entangled or not, is a fundamental problem in quantum information theory. We propose a powerful and computationally simple…
Optimal entanglement witnesses based on local orthogonal observables
Cheng-Jie Zhang, Yong-Sheng Zhang, Shun Zhang +1
We show that the entanglement witnesses based on local orthogonal observables which are introduced in [S. Yu and N.-L. Liu, Phys. Rev. Lett. 95, 150504 (2005)] and [O. Gühne, M. Me…
Compatibility conditions from multipartite entanglement measures
Jian-Ming Cai, Zheng-Wei Zhou, Shun Zhang +1
We consider an arbitrary d_{1}\otimes d_{2}\otimes ... \otimes d_{N} composite quantum system and find necessary conditions for general m-party subsystem states to be the reduced s…
