    "abstract": "We propose a scheme for measuring the squeezing, purity, and entanglement of\nGaussian states of light that does not require homodyne detection. The\nsuggested setup only needs beam splitters and single-photon detectors. Two-mode\nentanglement can be detected from coincidences between photodetectors placed on\nthe two beams.",
