Abstract

We consider the evolution of an arbitrary quantum dynamical semigroup under frequent kicks, where each kick is a generic quantum operation. We develop a generalization of the Baker-Campbell-Hausdorff formula allowing to reformulate such pulsed dynamics as a continuous one. This reveals an adiabatic evolution. We obtain a very general type of quantum Zeno dynamics, which unifies all known manifestations in the literature as well as describing new types.
