摘要
我们考虑一个原子 - 场耦合系统，其中两对四能级原子分别由激光场驱动，并囚禁在两个由光纤连接的远距离腔中。首先，我们证明了在适当条件下可以构造一个有效的压缩库。随后，我们证明了通过绝热地沿闭合回路操控该 engineered reservoir，可以在两个腔中的原子间实现两量子比特几何 CPHASE 门。该方案将环境工程、无退相干空间与几何相位量子计算相结合，具有显著特征：仅需改变驱动场的强度和相对相位，即可实现具有任意相位移动的 CPHASE 门。

4 pages, 2 figures; v2, We have maken considerable changes. New model to engineer effective reservoir without broadband squeezing light is proposed, which makes the scheme more practical. Main results are not changed; v3, accepted for PRA. Change style to PRA
