Abstract
In this work, we study the entropy squeezing of a two-level atom interacting with a single-mode quantum field by a multi-photon Jaynes-Cummings Model in the presence of the two-state random phase telegraph noise. We show that the entropy squeezing is very sensitive to the noise. It disappears in time quickly due to the strongly destructive effect of the noise.

The atomic squeezing properties were studied on the base of the Heisenberg uncertainty relation (HUR)
These works reveal that the entropy squeezing based on the entropic uncertainty relation (EUR) is more precise than the variance squeezing based on the HUR, as a measure of the atomic squeezing
Summary
The Jaynes-Cummings Model (JCM) [1, 2, 3] is the basic model for describing the interaction of a two-level atom with a single-mode cavity quantum ...eld under the rotating-wave approximation. The atomic squeezing properties were studied on the base of the Heisenberg uncertainty relation (HUR). The entropy squeezing of the atom has been studied extensively [15, 16, 17, 18, 19]. These works reveal that the entropy squeezing based on the EUR is more precise than the variance squeezing based on the HUR, as a measure of the atomic squeezing.
