利用二能级原子与腔场的共振相互作用Jaynes-Cummings(J-C)模型,制备出原子与光场的纠缠态,通过改变相互作用时间,可以控制纠缠态的纠缠程度.提出了利用这个原子与光场的非最大纠缠态,通过大失谐的J-C模型传送腔场的薛定谔猫态的方案.

The entangled state of atom cavity field is prepared based on the Jaynes Cummings model of two level atom cavity resonant interaction. Through changing the interaction times, the entanglement degree of the entangled state can be controlled. A scheme is proposed for teleportation of Schrodinger cat state of cavity field by using the non maximally entangled atom cavity states via the J C model with large detuning.
