Multipartite concurrence of W-class states based on sub-partite quantum systems
Wei Chen, Yanmin Yang, Shao-Ming Fei +2
We study the concurrence for arbitrary N-partite W-class states based on the (N-1)-partite partitions of subsystems by taking account to the structures of W-class states. By using…
