Research output: Chapter in Book/Report/Conference proceedingConference contribution


We investigate the entanglement dynamics of two quasi-degenerate qubits interacting with a quantized oscillator in a parameter regime where the rotating wave approximation breaks down. Analytical formulas for collapse and revival of entanglement are derived. OCIS codes: 270.5585 Quantum information and processing; 030.1670 Coherent optical effects.
