Evaluable multipartite entanglement measures: are multipartite concurrences entanglement monotones?
arXiv:quant-ph/0607084 · doi:10.1103/PhysRevA.74.052303
Abstract
We discuss the monotonicity under local operations and classical communication (LOCC) of systematically constructed quantities aiming at quantification of entanglement properties of multipartite quantum systems. The so-called generalized multipartite concurrences can qualify as legitimate entanglement measures if they are monotonous under LOCC. In the paper we give a necessary and sufficient criterion for their monotonicity.
