Separable Multipartite Mixed States - Operational Asymptotically
Necessary and Sufficient Conditions
Fernando G. S. L. Brandao, Reinaldo O. Vianna
abstract: We introduce an operational procedure to determine, with arbitrary
probability and accuracy, optimal entanglement witness for every multipartite
entangled state. This method provides an operational criterion for separability
which is asymptotically necessary and sufficient. Our results are also
generalized to detect all different types of multipartite entanglement.
