Abstract
We study the quantum Markovian master equation for a two level system in presence of coherent control. We show that its behavior is essentially determined by the complete positivity assumption of the quantum dynamical semigroup and that unitary control cannot modify its irreversibility character. Control theory provides several controllability-type condition´s able to capture the peculiarity of such driven system.
