    "abstract": "When a single photon is split by a beam splitter, its two `halves\u0027 can\nentangle two distant atoms into an EPR pair. We discuss a time-reversed\nanalogue of this experiment where two distant sources cooperate so as to emit a\nsingle photon. The two `half photons,\u0027 having interacted with two atoms, can\nentangle these atoms into an EPR pair once they are detected as a single\nphoton. Entanglement occurs by creating indistinguishabilility between the two\nmutually exclusive histories of the photon. This indistinguishabilility can be\ncreated either at the end of the two histories (by `erasing\u0027 the single\nphoton\u0027s path) or at their beginning (by `erasing\u0027 the two atoms\u0027 positions).",
