Quantifying Entanglement with Witness Operators
Fernando Guadalupe Santos Lins Brandao
We present an unifying approach to the quantification of entanglement based on entanglement witnesses, which includes several already established entanglement measures such as the…
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…
