  In this paper, we study the effect of classical driving field on the
spontaneous emission spectrum of a qubit embedded in a dissipative cavity.
Furthermore, we monitor the entanglement dynamics of the driven qubit with its
radiative decay under the action of the classical field. Afterwards, we carry
out an investigation on the possibility of entanglement swapping between two
such distinct driven qubits. The swapping will be feasible with the aid of a
Bell state measurement performing on the photons leaving the cavities. It is
demonstrated that the classical driving field has a beneficial effect on the
prolonging of the swapped entanglement.
