对腔外原子操作时腔内原子的发射性质(英文)

考虑初始处于W态的三个双能级原子,将其中两个分别注入处于真空态的两个腔中,发生共振相互作用。通过对腔外原子进行适当的旋转及测量,可使腔场发射双模压缩光,并且当旋转角度发生变化时,压缩的程度也会发生变化。

腔外原子选择测量对腔内原子量子性质的调控

考虑了2个初始处于纠缠态的级联三能级原子,将其中一个原子注入高Q腔中与单模压缩真空场发生共振相互作用。利用全量子理论和数值计算方法研究了腔外原子的选择测量对腔内原子偶极振幅平方压缩的影响。结果表明,通过对腔外原子进行选择性测量,可调控腔内原子的偶极振幅平方压缩。

The emission properties of an atom inside a cavity when manipulating the atoms outside the cavity

Considering three two-level atoms initially in the GHZ state, then one atom of them is put into an initially empty cavity and made resonant interaction. It is shown that the emission properties of the atom inside the cavity can be affected only when both of the atoms outside the cavity have been manipulated. This conclusion can also be generalized to n two-level atoms.
