Concurrence for multipartite states
arXiv:quant-ph/0608224 · doi:10.1088/0305-4470/39/49/010
Abstract
We construct a generalized concurrence for general multipartite states based on local W-class and GHZ-class operators. We explicitly construct the corresponding concurrence for three-partite states. The construction of the concurrence is interesting since it is based on local operators.
