International Journal of Theoretical Physics Aims and scope Submit manuscript

Abstract

We study atomic state transfer and entanglement generation when the N atomic ensemble is trapped in two coupled cavities. We show that based on the collective interaction between the atoms and local cavity fields an ideal quantum state transfer can be realized if some special conditions are satisfied. In addition, the maximal atom entangled state can be achieved. The effect of the cavity losses on the quantum processes is also studied.
