Abstract

In this paper,we introduce a system containing of two qubits interacting with a cavity which interacted with a reservoir. Using the Fano technique we will show this system is equivalent with two qubits which are interacting with a common heat bath. We also add a laser field and the behavior of this system is investigated when the qubits are dissipative. In this way we show that the presence of laser field can generate a high entanglement in this system, in other word the pump of energy using the laser field can compensate for the lose of dissipation of qubits. We also show that our system is almost insensible to temperature.
