    "abstract": "A new scheme is described for pulsed squeezed light generation using\nfemtosecond pulses parametrically deamplified through a single pass in a thin\n(0.1mm) potassium niobate KNbO3 crystal, with a significant deamplification of\nabout -3dB. The quantum noise of each individual pulse is registered in the\ntime domain using a single-shot homodyne detection operated with femtosecond\npulses and the best squeezed quadrature variance was measured to be 1.87 dB\nbelow the shot noise level. Such a scheme provides the basic ressource for\ntime-resolved quantum communication protocols.",
