We introduce a scheme for creating continuous variable entanglement between an atomic beam and an optical field, by using squeezed light to outcouple atoms from a Bose-Einstein condensate via a Raman transition. We model the full multimode dynamics of the atom laser beam and the squeezed optical field and show that, with appropriate two-photon detuning and two-photon Rabi frequency, the transmitted light is entangled in amplitude and phase with the outcoupled atom laser beam. The degree of entanglement is controllable via changes in the two-photon Rabi frequency of the outcoupling process.
我们提出了一种通过利用压缩光经由拉曼跃迁从玻色 - 爱因斯坦凝聚体中输出原子，从而在原子束与光场之间创建连续变量纠缠的方案。我们对原子激光束和压缩光场的完整多模动力学进行了建模，并表明，通过适当的双光子失谐和双光子拉比频率，透射光在幅度和相位上与输出的原子激光束纠缠在一起。纠缠程度可通过改变输出耦合过程的双光子拉比频率来控制。
