Resumo
In the present work, we theoretically study the entropy of a Cooper pair box coupled to a (single mode) of one-dimensional transmission line resonator. The proposed scheme uses the Jaynes-Cummings model in presence of losses to study the time evolution of the system entropy. The coupling of these two subsystems provides an important indication of the influence of a Cooper pair box on the evolution of system entropy. Decaying CPB allows us to control the variation of entropy at certain times.
