CLASSICAL INFORMATION ENTROPY AND WIGNER FUNCTION EVOLUTION OF RANDOM PHASE NEGATIVE BINOMIAL OPTICAL FIELDS IN THERMAL CHANNEL

Abstract

The Wehrl classical information entropy of random phase negative binomial states (RPNBS) is investigated, and their Wigner function evolution in the thermal environment is also discussed. It is shown that the evolution of the RPNBS in the thermal channel can be roughly regarded as the shift of the parameters ε and α0 of the RPNBS.
