| Abstract: | The position and momentum entropic squeezing of even and odd coherent states are studied. The relations between the two entropic squeezings and the two quadrature components squeezing are also discussed. The results show that even and odd coherent state exhibits both position and momentum entropic squeezing, which is different from the standard deviations squeezing. |
