DYNAMICAL BEHAVIORS OF THE WIGNER FUNCTION OF EXCITED BINOMIAL STATES IN THERMAL CHANNEL
Shan-Hai Mei, Shangbin Li · Modern Physics Letters B · 2009
In this paper, we investigate the non-classicality of excited binomial states by analyzing the partial negativity of the Wigner function. The volume of the negative part of the Wigner function is numerically calculated for some single-photon-excited binomial states. The dynamical behaviors of the Wigner distribution of excited binomial states in the thermal channel are investigated.
