    "abstract": "We have reconstructed the quantum state of optical pulses containing single\nphotons using the method of phase-randomized pulsed optical homodyne\ntomography. The single-photon Fock state |1\u003e was prepared using conditional\nmeasurements on photon pairs born in the process of parametric down-conversion.\nA probability distribution of the phase-averaged electric field amplitudes with\na strongly non-Gaussian shape is obtained with the total detection efficiency\nof (55+-1)%. The angle-averaged Wigner function reconstructed from this\ndistribution shows a strong dip reaching classically impossible negative values\naround the origin of the phase space.",
