反J-C模型调控纠缠原子量子特性

单个二能级原子在强经典驱动和大失谐的双重条件下,系统可以等效化为反J-C模型.在此模型中将一对纠缠二能级原子中的一个注入该腔中,演化之后,对腔外原子做选择性测量,可以调控腔内原子的布居和偶极压缩.经过研究发现利用此种方法来远程调控原子的布居和偶极压缩效果更佳.

Control of Quantum Properties of Entanglement Atom with Anti-J-C Model

A two energy level atom can be converted into anti-J-C model equivalently under the condition of strong driven classical field and large detuning.One of the couple of entangled two-level atoms is poured into the cavity in this model.After the evolution,the atom out of the cavity is selectively measured,the occupancy and the dipole squeezing of the atom in the cavity can be controlled.It is found that the result is better in this way for controlling the occupancy and the dipole squeezing of the atom remotely.
