    "abstract": "Quantum theory predicts that two indistinguishable photons incident on a\nbeam-splitter interferometer stick together as they exit the device (the pair\nemerges randomly from one port or the other). We use a special\nphoton-number-resolving energy detector for a direct loophole-free observation\nof this quantum-interference phenomenon. Simultaneous measurements from two\nsuch detectors, one at each beam-splitter output port, confirm the absence of\ncross-coincidences.",
