Classical entropy of quantum states of light
Arkadiusz Orłowski · Physical Review A · 1993
Classical-like, Wehrl's entropies of various quantum states of light are calculated and investigated as functions of the average value of the photon-number operator. Qualitatively similar behavior of the Wehrl entropies, corresponding to quantum states with quite different properties, is observed. A type of damping of the Wehrl entropies for states with high coherent components is pointed out and discussed.
