Hong-Ou-Mandel interferometry with cavity QED-based single-photon sources: A Quantum Jump Analysis

arXiv:2507.03803 · doi:10.1364/JOSAB.572714

Abstract

We present a quantum jump/trajectory analysis of the two-photon interference phenomenon in the context of the Hong-Ou-Mandel effect (HOME). In particular, we consider the standard setup of HOME, which consists of two-photon sources firing single photons from the opposite sides of a 50/50 beam splitter and two perfect detectors placed at the output ports to record photodetection events. For single-photon sources, we consider two special cases: (1) two excited two-level atoms and (2) two atom-cavity setups with initially present single photons in both cavities. For both cases, we report analytic results as well as quantum jump-based Monte Carlo simulations to demonstrate the signatures of these single-photon sources on the HOME under different working conditions (for example, strong- and weak-coupling regimes of cavity quantum electrodynamics). Our results may have interesting applications in linear optics quantum computing as well as in protocols that test the indistinguishability of single-photon sources.
