论文摘要
我们提出了一个单原子，腔量子电动力学系统，与最近证明的纤维集成微型和纳米腔设置兼容，用于按需光学数量状态的按需生产，$ 0N $ -STATE，以及二项式代码脉冲。该方案利用在整个原子基态超精细水平内使用拉曼过渡，并且在激光和空腔场中运行的是，从原子过渡中引起的激光和腔场远比激发态超精美的超精细分裂。这使动力学将动力学降低到一个简单的，腔抑制的塔维斯 - 阵线模型的动力学，其集体自旋由地面超精细水平的总角动量确定。
We propose a single-atom, cavity quantum electrodynamics system, compatible with recently demonstrated, fiber-integrated micro- and nano-cavity setups, for the on-demand production of optical number-state, $0N$-state, and binomial-code-state pulses. The scheme makes use of Raman transitions within an entire atomic ground-state hyperfine level and operates with laser and cavity fields detuned from the atomic transition by much more than the excited-state hyperfine splitting. This enables reduction of the dynamics to that of a simple, cavity-damped Tavis-Cummings model with the collective spin determined by the total angular momentum of the ground hyperfine level.
