Abstract
A quantum phase space entropy is defined, which directly reflects the global dynamical properties of the system similar to the synoptic view of several classical trajectories in a Poincare section. The quantum results allow a direct comparison with a corresponding purely classica l entropy. Numerical results for a periodically driven rotor illustrat e the usefulness of phase space entropies for systems with mixed chaot ic and regular dynamics.
