论文摘要
我们研究了雷德伯格电磁诱导的透明度，通过冷rydberg原子合体传播的弱相干脉冲的光子统计数据。我们在实验上表明，发射光的二阶自相关函数的值很大取决于脉冲内的位置，并且在脉冲瞬态期间很大变化。特别是，我们表明，传输脉冲的落边缘显示的值比脉冲的其余部分低得多。我们得出了一个理论模型，该模型可以定量预测我们的结果并解释所涉及的身体行为。最后，我们使用这种效果来生成来自原子集合中脉冲内的单个光子。我们表明，仅选择传输脉冲的最后一部分，单个光子显示的抗挑战参数低至0.12，每次试验的产生效率比具有原子合体的概率生成方案大于可能。
We study the photon statistics of weak coherent pulses propagating through a cold Rydberg atomic ensemble in the regime of Rydberg electromagnetically induced transparency. We show experimentally that the value of the second-order autocorrelation function of the transmitted light strongly depends on the position within the pulse and heavily varies during the transients of the pulse. In particular, we show that the falling edge of the transmitted pulse displays much lower values than the rest of the pulse. We derive a theoretical model that quantitatively predicts our results and explains the physical behavior involved. Finally, we use this effect to generate single photons localized within a pulse from the atomic ensemble. We show that by selecting only the last part of the transmitted pulse, the single photons show an antibunching parameter as low as 0.12 and a generation efficiency per trial larger than possible with probabilistic generation schemes with atomic ensembles.
