光学读出是原子态测量的基础工具，但其保真度常受限于不完善的光子收集。当读出在循环跃迁上进行时，该跃迁会在共振激发下持续发荧光，从而增加信号并实现单次读出，这一问题可得到缓解。我们提出一种通过虚假衰变路径间的相消干涉来提高原子跃迁循环性的方法，描述了可实施该方法的原子系统特征，并对多个实例进行建模，其中发射光子的数量提高了多个数量级。
英文摘要
Optical readout is a fundamental tool in atomic state measurement, yet the fidelity of optical readout is frequently limited by imperfect photon collection. This can be mitigated when readout occurs on a cycling transition which continuously fluoresces under resonant excitation, thus increasing signal and enabling single-shot readout. We present a method to extend the cyclicity of atomic transitions via coherent destructive interference between spurious decay paths. We describe the characteristics of atomic systems in which this method can be implemented and model several examples in which the number of emitted photons is increased by multiple orders of magnitude.
