On the structure of quantum Markov semigroups

Appears in collection : PRACQSYS 2018: Principles and Applications of Control in Quantum Systems

We discuss the relationships between the decoherence-free subalgebra and the structure of the fixed point subalgebra of a quantum Markov semigroup on B(h) with a faithful normal invariant state. We show that atomicity of the decoherence-free subalgebra is equivalent to typical splittings of B(h) into the a subalgebra where maps of the semigroup acts as endomorphisms and a remainder space. More-over, we characterize the set of reversible states.
