    "abstract": "We introduce the entangled coherent state representation, which provides a\npowerful technique for efficiently and elegantly describing and analyzing\nquantum optics sources and detectors while respecting the photon number\nsuperselection rule that is satisfied by all known quantum optics experiments.\nWe apply the entangled coherent state representation to elucidate and resolve\nthe longstanding puzzles of the coherence of a laser output field, interference\nbetween two number states, and dichotomous interpretations of quantum\nteleportation of coherent states.",
