| 摘 要： | 在双模腔中,利用循环布局跃迁的人工原子,给出了实现腔模场频率上转换和下转换的方案.其中,腔模和经典场与三能级人工原子的相互作用都是共振耦合.因此,系统的量子动力学操作处于较高的速度进行.从抑制退相干的角度看,这是非常有意义的.结果表明,制备人工原子在某个初态,可以实现腔模频率上转换和下转换操作.最后,简单说明了从腔模场的任意初态可产生双模压缩态.

| Abstract: | Using a strong driving classical field, we propose experimental schemes for realizing frequency up-and down-conversion in a two-mode cavity by an artificial atom with cyclic population transfer. Our scheme is based on resonant interaction of the cavity modes with a single driven three-level artificial atom, so that the quantum dynamic operation is at a high speed, which is important in view of decoherence. It is shown that frequency up- and down-conversion operations can be realized by initially preparing t... |
