Uncertainty relations and the Wehrl entropy — •Kedar S. Ranade and Wolfgang P. Schleich — Institut für Quantenphysik, Universität Ulm

In 1979, A. Wehrl introduced the concept of classical entropies of a quantum state and demonstrated several properties of these entropies. In this talk, we investigate generalisations of the Wehrl entropy with respect to quantum-mechanical uncertainty relations for systems with continuous variables. In important cases, the relevant quantities can be measured with standard techniques from quantum optics.
