Non-Markovian random unitary qubit dynamics
Dariusz Chruściński, Filip A. Wudarski
We compare two approaches to non-Markovian quantum evolution: one based on the concept of divisible maps and the other one based on distinguishability of quantum states. The former…

Indecomposable optimal entanglement witnesses in C4 {\otimes} C4
Dariusz Chruściński, Filip A. Wudarski
We provide two 1-parameter families of indecomposable entanglement witnesses in C4 {\otimes} C4. Following recent paper by Ha and Kye [Phys. Rev. A 84, 024302 (2011)] we show that…

Geometry of entanglement witnesses parameterized by SO(3) group
Dariusz Chruściński, Filip A. Wudarski
We characterize a set of positive maps in matrix algebra of 4x4 complex matrices. Equivalently, we provide a subset of entanglement witnesses parameterized by the rotation group SO…
