On Bipartite Operators Defined by Completely Different Permutations

Marek Mozrzymas, Dariusz Chruściński, Gniewomir Sarbicki

We introduce a class of bipartite operators acting on $H \otimes H$ ( $H$ being an $n$ -dimensional Hilbert space) defined by a set of $n$ Completely Di…

A class of bistochastic positive optimal maps in $M_{d} (C)$

Adam Rutkowski, Gniewomir Sarbicki, Dariusz Chruściński

We provide a straightforward generalization of a positive map in $M_{3} (C)$ considered recently by Miller and Olkiewicz \cite{Miller}. It is proved that these maps are optim…

Exposed positive maps in M_4(C)

Dariusz Chruściński, Gniewomir Sarbicki

It is shown that the family of so called Breuer-Hall maps in M_4(C) possesses strong spanning property and hence they are exposed in the convex cone of positive maps in M_4(C)
