In this paper, we investigate the dynamics of coded information in a single Cooper pair interacting with a single Cavity mode. The effect of the relative ratio of Josephson junction capacity and the gate capacities on the purity, coherent vectors and the entropy of the travelling Cooper pair are investigated. The exchange information between the environment and the Cooper pair is quantified for different values of the Cooper qubit and environment parameters. © 2012 Springer Science+Business Media New York.
