被捕获在光腔模式内的单个铯原子被用于根据需要产生单个光子。光子波包作为高斯光束发射，具有时间分布。LE和重复率由外部驱动场控制。每次产生尝试被推断为以接近1的概率成功，而在总腔输出中产生非偏振光子的效率为0.69 +/- 0.10，这受到被动腔损耗的限制。每个被捕获的原子平均产生1.4 × 10（4）个光子。这些结果构成了量子信息科学的重要一步，例如，实现分布式量子网络。
A single cesium atom trapped within the mode of an optical cavity is used to generate single photons on demand. The photon wave packets are emitted as a Gaussian beam with temporal pro. le and repetition rate controlled by external driving fields. Each generation attempt is inferred to succeed with a probability near unity, whereas the efficiency for creating an unpolarized photon in the total cavity output is 0.69 +/- 0.10, as limited by passive cavity losses. An average of 1.4 x 10(4) photons are produced by each trapped atom. These results constitute an important step in quantum information science, for example, toward the realization of distributed quantum networking.
