摘要

Dynamic evolutions of the quantum discord and entanglement between two charge qubits located inside a damped cavity are demonstrated analytically. It is found that with cavity dissipation, the dynamics of the quantum discord between two qubits is sensitive to the degree of mixing of the initial qubits' state. This is different from steady entanglement, which is independent of the degree of mixing of the initial state of the qubits.
