Environment-induced quantum correlations in a driven two-qubit system

We study the generation of quantum correlations between two qubits coupled to a common non-Markovian environment and driven by a classical external field. It is shown that both the classical driving field and the non-Markovian properties play a key role in improving entanglement and geometric quantum discord as well as Bell nonlocality. Moreover, the dual role of detuning Δ between qubits and the driving field in the creation of quantum correlations is also demonstrated. (paper)
