We investigate the entropy squeezing of the nonlinear k-quantum JC model.A definition of squeezing is presented for this system based on the quantum information theory.The utility of the Definition is Illustrated by examining squeezing in the information entropy of a nonlinear k-quantum two-level atom.The influence of the atomic coherence and the detuning parameter on the properties of the information entropy and squeezing of the atomic variables is examined.
