Indistinguishability of single photons from independent sources is critically important for scalable quantum technologies. We provide a comprehensive comparison of single-photon indistinguishability of different kinds of cavity quantum electrodynamics (CQED) systems by numerically simulating Hong-Ou-Mandel (HOM) two-photon interference. We find that the CQED system using nature atoms exhibit superiority in indistinguishability, benefiting from the inherently identical features. Moreover, a $\Lambda-$type three-level atoms show essential robust against variation of various system parameters because it exploits the two ground states with considerable smaller decay rates for single-photon generation. Furthermore, a machine learning-based framework is proposed to significantly and robustly improve single-photon indistinguishability for non-identical two CQED systems. This work may pave the way for designing and engineering reliable and scalable photon-based quantum technologies. |
