利用原子的缀饰态和压缩变换腔模，分析了三能级$\ensuremath{\Lambda}$和V原子系统中四波混频的量子关联.发现了两个耗散通道，通过这两个通道，修饰原子同时吸收来自压缩变换模对的激发。在两个通道的存在下，纠缠得到了极大的增强，最佳可达态接近于原始的Einstein-Podolsky-罗森纠缠态。该方案适用于光学制度，原子的自发辐射必须考虑，不像两步原子水库工程计划，这是有限的微波政权。
We analyze quantum correlations in four-wave mixing in three-level $\ensuremath{\Lambda}$ and V atomic systems by using dressed atomic states and squeeze-transformed cavity modes. Two dissipation channels are identified, through which the dressed atoms simultaneously absorb in the excitations from the pair of squeeze-transformed modes. It is in the presence of two channels that the entanglement is greatly enhanced and the best achievable state approaches the original Einstein-Podolsky-Rosen entangled state. This scheme is applicable in the optical regime where atomic spontaneous emission has to be taken into account, unlike the two-step atomic reservoir engineering scheme, which is limited to the microwave regime.
