Evaluable multipartite entanglement measures: are multipartite
concurrences entanglement monotones?
Rafal Demkowicz-Dobrzanski, Andreas Buchleitner, Marek Kus, Florian Mintert
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.
