Abstract:We investigate the influence of time-dependent electromagnetic field on the geometric quantum correlation and quantum coherence between two superconducting qubits in an open superconducting quantum circuit system. It is shown that the freezing of geometric quantum correlation will occur after the addition of magnetic field, and the freezing time will be extended with the addition of time-dependent electromagnetic field. In addition, the influence of time-dependent electromagnetic field on the quantum information flow between superconducting qubits and the environment is discussed by using trace distance method. It is found that the time-dependent electromagnetic fields can suppress the effect of the environment and slow down the exchange of the quantum information flows between the superconducting qubits and the environment.
