Resumo
We investigate entanglement and mixedness of a superconducting qubit coupled to the damped cavity field. We introduce a new measure for the mixedness and find that the phase damping of the cavity leads to simultaneous long-death of the entropy squeezing, the purity of the qubit states, and the entanglement of the field–qubit system.
