Periodic revival of entanglement of two strongly driven qubits in a dissipative cavity

We study the dynamics and decoherence of a system of two strongly driven qubits in a dissipative cavity. The two qubits have no direct interaction and are individually off-resonantly coupled to a single mode of quantized radiation. We derive analytical solutions to the Lindblad-type master equation...

Description
Summary:We study the dynamics and decoherence of a system of two strongly driven qubits in a dissipative cavity. The two qubits have no direct interaction and are individually off-resonantly coupled to a single mode of quantized radiation. We derive analytical solutions to the Lindblad-type master equation and study the evolution of the entanglement of this system. We show that with non-zero detuning between the quantum and classical fields, the initial decay of the entanglement is followed by its revival periodic in time. We show that different Bell states follow evolutions with different rates.
