Abstract

Several expressions for quantum entropy proposed in the literature are evaluated within the Weyl—Wigner—Moyal phase-space representation of quantum mechanics, with emphasis on some important subtle points in this approach. It has been found that the Rényi—Süßmann entropy and its linearization are distinguished because of their properties.
