    "abstract": "We investigate the mutual information and entanglement of stationary state of\ntwo locally driven qubits under the influence of collective dephasing. It is\nshown that both the mutual information and the entanglement of two qubits in\nthe stationary state exhibit damped oscillation with the scaled action time\n$\\gamma{T}$ of the local external driving field. It means that we can control\nboth the entanglement and total correlation of the stationary state of two\nqubits by adjusting the action time of the driving field. We also consider the\ninfluence of collective dephasing on entanglement of two qutrits and obtain the\nsufficient condition that the stationary state is entangled.",
