论文摘要
被困的原子集合是一种方便的系统，用于在电子接地状态的长期寿命级上存储量子信息，及其转换以通过刺激的拉曼工艺传播光光子。在这里，我们研究了相干制备的原子集合的光子的相匹配发射。我们考虑具有正常密度分布的细长谐波陷阱中冷原子的合奏，并确定近似光学元件的参数以匹配发射辐射的模式几何形状并最佳地将其收集到光学波导中。
Trapped atomic ensembles are convenient systems for quantum information storage in the long-lived sublevels of the electronic ground state and its conversion to propagating optical photons via stimulated Raman processes. Here we investigate a phase-matched emission of photons from a coherently prepared atomic ensemble. We consider an ensemble of cold atoms in an elongated harmonic trap with normal density distribution, and determine the parameters of paraxial optics to match the mode geometry of the emitted radiation and optimally collect it into an optical waveguide.
