Wehrl's Entropy and Noise
Wu He-jun, Yun‐Jie Xia · Chinese Physics Letters · 1997
The relations between Wehrl's entropy and squeezing or total noise in the field with Gaussian Q function are established. The results show that, the Wehrl's entropy will be reduced when the squeezing is increased or the total noise is decreased. The other nonclassical properties in this kind of field are also discussed.
