Witnessed Entanglement
Fernando G. S. L. Brandao, Reinaldo O. Vianna
We present a new measure of entanglement for mixed states. It can be approximately computable for every state and can be used to quantify all different types of multipartite entang…
Separable Multipartite Mixed States - Operational Asymptotically Necessary and Sufficient Conditions
Fernando G. S. L. Brandao, Reinaldo O. Vianna
We introduce an operational procedure to determine, with arbitrary probability and accuracy, optimal entanglement witness for every multipartite entangled state. This method provid…
A Robust Semidefinite Programming Approach to the Separability Problem
Fernando. G. S. L. Brandao, Reinaldo O. Vianna
We express the optimization of entanglement witnesses for arbitrary bipartite states in terms of a class of convex optimization problems known as Robust Semidefinite Programs (RSDP…
