Comparing the effects of atomic damping and velocity fluctuations upon transfer of quantum state in a bimodal cavity QED

摘要

In the present work we study the influence of both the fluctuation effects of the atom velocity and the atomic decay on the fidelity corresponding to a protocol for the quantum state transfer between two modes of a bimodal cavity QED. In our model the atom interacts separately with each mode, which is made possible by applying the Stark shift effect on the atomic-levels to tuning (detuning) properly modes A and B.
