Completely positive dynamical semigroups of N -level systems
Vittorio Gorini, Andrzej Kossakowski, E. C. G. Sudarshan
We establish the general form of the generator of a completely positive dynamical semigroup of an N-level quantum system, and we apply the result to derive explicit inequalities among the physical parameters characterizing the Markovian evolution of a 2-level system.
