Entropic Squeezing for the Superposition State of the Vacuum and the Fock State
Hongcai Li · Journal of Fujian Normal University · 2004
The entropic squeezing for the superposition state of the vacuum and the Fock state |n is studied, and compared with the quadrature squeezing. The results show that: when the variance n=1,2, the superposition state is squeezing, and the entropic squeezing is more sensitive than quadrature squeezing for the squeezing effect of the field ; when n≥3, with the increasing of variance n, it isn't squeezing.
