Anti-Hong–Ou–Mandel interference by coherent perfect absorption of entangled photons
Anti-Hong–Ou–Mandel interference by coherent perfect absorption of entangled photons
Abstract Two-photon interference, known as the Hong–Ou–Mandel effect, has colossal implications for quantum technology. It was observed in 1987 with two photodetectors monitoring outputs of the beamsplitter illuminated by photon pairs: the coincidence rate of the detectors drops to zero when detected photons overlap in time. More broadly, bosons (e.g. …
