Transient entropy squeezing of a single-Cooper-pair box placed inside a phase-damped cavity

This article provides a convenient framework for a quantitative evaluation of the transient entropy squeezing generated when a single-Cooper-pair box irradiated by a classical field taking into account a phase-damped cavity. It explores how the entropy squeezing factors influenced by phase-damped cavity. The numerical results reveal an interesting connection between entropy squeezing and entanglement dynamics.
