Generalized Pauli channels and a class of non-Markovian quantum evolution
Dariusz Chruściński, Katarzyna Siudzińska
We analyze the quantum evolution represented by a time-dependent family of generalized Pauli channels. This evolution is provided by the random decoherence channels with respect to…
Markovian semigroup from non-Markovian evolutions
F. A. Wudarski, D. Chruściński
It is shown that a convex combination of two non-Markovian evolutions may lead to Markovian semigroup. This shows that convex combination of quantum evolutions displaying nontrivia…
Generalising Wigner's theorem
Gniewomir Sarbicki, Dariusz Chruściński, Marek Mozrzymas
We analyse linear maps of operator algebras mapping the set of rank- projectors onto the set of rank- projectors surjectively. We give a complete…
Sufficient conditions for memory kernel master equation
Dariusz Chruściński, Andrzej Kossakowski
We derive sufficient conditions for the memory kernel which guarantee legitimate (completely positive and trace-preserving) dynamical map. It turns out that these conditions provid…
