    "abstract": "We report the first experimental demonstration of conditional preparation of\na non classical state of light in the continuous variable regime. Starting from\na non degenerate OPO which generates above threshold quantum intensity\ncorrelated signal and idler \"twin beams\", we keep the recorded values of the\nsignal intensity only when the idler falls inside a band of values narrower\nthan its standard deviation. By this very simple technique, we generate a\nsub-Poissonian state 4.4dB below shot noise from twin beams exhibiting 7.5dB of\nnoise reduction in the intensity difference.",
