Classical information entropy for single and two mode quantum fields
W. Leoński, Adam Miranowicz, K. Piatek · Proceedings of SPIE, the International Society for Optical Engineering/Proceedings of SPIE · 2003
The classical information entropy defined by Wehrl in terms of the Husimi Q-function is discussed and generalized over the concepts of the Wehrl phase distribution, and the Wehrl intermode-correlation parameters. The classical entropic functions are applied to describe the quantum properties of single and/or two-mode optical fields.
