We propose schemes for the unconditional preparation of a two-mode squeezed state of effective bosonic modes realized in a pair of atomic ensembles interacting collectively with optical cavity and laser fields. The scheme uses Raman transitions between stable atomic ground states and under ideal conditions produces pure entangled states in the steady state. The scheme works both for ensembles confined within a single cavity and for ensembles confined in separate, cascaded cavities.
我们提出了一些方案，用于无条件制备有效玻色子模的双模压缩态，该态在与光腔和激光场集体相互作用的一对原子系综中实现。该方案利用稳定原子基态之间的拉曼跃迁，在理想条件下，在稳态中产生纯纠缠态。该方案既适用于限制在单个腔内的系综，也适用于限制在单独的级联腔内的系综。
