Hong–Ou–Mandel interferometry with cavity QED-based single-photon sources: a quantum jump analysis
Year: 2025
Type: article
Abstract: We present a quantum jump/trajectory analysis of the two-photon interference phenomenon in the context of the Hong–Ou–Mandel (HOM) effect. In particular, we consider the standard setup of the HOM effect, which consists of two-photon sources firing single photons from 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 HOM effect under different working conditions (e.g., strong- and weak-coupling regimes of cavity quantum electrodynamics). The HOM effect offers applications in the areas of linear optics quantum computing, as well as in protocols that test the indistinguishability of single-photon sources.
