Abstract
We revisit the phenomenon of quantum stochastic resonance in the regime of validity of the Bloch equations. We find that a stochastic resonance behavi or in the steady-state response of the system is present whenever the noise -induced relaxation dynamics can be characterized via a single relaxation t ime scale. The picture is validated by a simple nuclear magnetic resonance experiment on water.
