ENTANGLEMENT OF A SINGLE-MODE CAVITY QED OF A RAMAN INTERACTION
Mahmoud Abdel‐Aty, Faisal Al-Showaikh, Saad S. M. Hassan · International Journal of Quantum Information · 2007
We investigate the entanglement of a degenerate Raman process involving two degenerate Rydberg energy levels of an atom interacting with a single-mode cavity field. We use the concurrence as an entanglement measure and show that long living entanglement can be obtained for certain choices of the system parameters.
