    "abstract": "We present a continuous-variable experimental analysis of a two-photon Fock\nstate of free-propagating light. This state is obtained from a pulsed\nnon-degenerate parametric amplifier, which produces two intensity-correlated\ntwin beams. Counting two photons in one beam projects the other beam in the\ndesired two-photon Fock state, which is analyzed by using a pulsed homodyne\ndetection. The Wigner function of the measured state is clearly negative. We\ndeveloped a detailed analytic model which allows a fast and efficient analysis\nof the experimental results.",
