On exposed positive maps: Robertson and Breuer-Hall maps
Dariusz Chruściński
It is well known that so called Breuer-Hall positive maps used in entanglement theory are optimal. We show that these maps possess much more subtle property --- they are exposed. A…

On measures of non-Markovianity: divisibility vs. backflow of information
Dariusz Chruściński, Andrzej Kossakowski, Ángel Rivas
We analyze two recently proposed measures of non-Markovianity: one based on the concept of divisibility of the dynamical map and the other one based on distinguishability of quantu…

A family of generalized Horodecki-like entangled states
Dariusz Chruściński, Adam Rutkowski
We provide a multi-parameter family of 2-qudit PPT entangled states which generalizes the celebrated Horodecki state in 3 x 3. The entanglement of this family is identified via sem…
