Structure of uniformly continuous quantum Markov semigroups
Julien Deschamps, Franco Fagnola, Emanuela Sasso, Veronica Umanità · Reviews in Mathematical Physics · 2016
The structure of uniformly continuous quantum Markov semigroups with atomic decoherence-free subalgebra is established providing a natural decomposition of a Markovian open quantum system into its noiseless (decoherence-free) and irreducible (ergodic) components. This leads to a new characterization of the structure of invariant states and a new method for finding decoherence-free subsystems and subspaces. Examples are presented to illustrate these results.
