The exact dynamics of two qubits driven by classical fields and embedded in two independent non-Markovian environments is investigated. Quite different from the results in the absence of classical driving fields, it is shown that the phenomena of single-qubit population trapping and two-qubit entanglement preservation occur in the non-Markovian regime. Moreover, we show that the negative influence of detuning between qubits and the driving fields on the population trapping and entanglement preservation can be suppressed by increasing the Rabi frequency. Finally, a physical explanation is given via the quasimode theory.
