💫 Hong-Ou-Mandel Photon Bunching

Fire two single photons into opposite ports of a 50:50 beamsplitter and watch quantum interference: when the photons are indistinguishable and arrive together they bunch out the same port, suppressing coincidence clicks — the Hong-Ou-Mandel dip that underlies photonic qubit gates.
