    "abstract": "Direct photon detection is experimentally implemented to measure the\nsqueezing and purity of a single-mode squeezed vacuum state without an\ninterferometric homodyne detection. Following a recent theoretical proposal\n[arXiv quant-ph/0311119], the setup only requires a tunable beamsplitter and a\nsingle-photon detector to fully characterize the generated Gaussian states. The\nexperimental implementation of this procedure is discussed and compared with\nother reference methods.",
