Abstract

To conveniently calculate the Wigner function of the optical cumulant operator and its dissipation evolution in a thermal environment,in this paper,the thermo-entangled state representation is introduced to derive the general evolution formula of the Wigner function,and its relation to Weyl correspondence is also discussed.The method of integration within the ordered product of operators is essential to our discussion.

Key words

Wigner function/optical cumulant operator/dissipation evolution/thermo-entangled state repre-sentation/integration within ordered product of operators
