Dissipative generators, divisible dynamical maps, and the Kadison-Schwarz inequality
Dariusz Chruściński, Farrukh Maksutovich Mukhamedov · Physical Review A · 2019
We introduce the concept of Kadison-Schwarz-divisible dynamical maps. It turns out that it is a natural generalization of the well-known CP-divisibility which characterizes quantum Markovian evolution. It is proved that Kadison-Schwarz-divisible maps are fully characterized in terms of time-local dissipative generators. Simple qubit evolution illustrates the concept.
