Quantum information and entropy squeezing of a two-level atom with a non-linear medium

Mahmoud Abdel‐Aty, M. Sebawe Abdalla, A.‐S. F. Obada

In the language of quantum information theory we study the entropy squeezing of a two-level atom in a Kerr-like medium. A definition of squeezing is presented for this system, based on information theory. The utility of the definition is illustrated by examining the entropy squeezing of a two-level atom with a Kerr-like medium. The influence of the non-linear interaction of the Kerr medium, the atomic coherence and the detuning parameter on the properties of the entropy and squeezing of the atomic variables is examined.
