Exposed positive maps: a sufficient condition
Dariusz Chruściński, Gniewomir Sarbicki
Exposed positive maps in matrix algebras define a dense subset of extremal maps. We provide a sufficient condition for a positive map to be exposed. This is an analog of a spanning…

Optimal entanglement witnesses for two qutrits
Dariusz Chruściński, Gniewomir Sarbicki
We provide a proof that entanglement witnesses considered recently in [D. Chruściński, F.A. Wudarski, arXiv:1105.4821] are optimal.

Optimal decomposable witnesses without the spanning property
Remigiusz Augusiak, Gniewomir Sarbicki, Maciej Lewenstein
One of the unsolved problems in the characterization of the optimal entanglement witnesses is the existence of optimal witnesses acting on bipartite Hilbert spaces H_{m,n}=C^m\otim…
