| Abstract: | The concept of entropic squeezing is established and the entropic squeezing of the field interacting with the atom is investigated by regarding the entropy as a measure of quantum fluctuation and according to entropy uncertainty relation. The results show that the entropic squeezing is a high sensitive measure for the squeezing effect of the field. |
