    "abstract": "We experimentally investigate a method of directly characterizing the photon\nnumber distribution of nonclassical light beams that is tolerant to losses and\nmakes use only of standard binary detectors. This is achieved in a single\nmeasurement by calibrating the detector using some small amount of prior\ninformation about the source. We demonstrate the technique on a freely\npropagating heralded two-photon number state created by conditional detection\nof a two-mode squeezed state generated by a parametric downconverter.",
