Query: Pulsed homodyne measurements of femtosecond squeezed pulses generated by
  single-pass parametric deamplification   A new scheme is described for pulsed squeezed light generation using
femtosecond pulses parametrically deamplified through a single pass in a thin
(0.1mm) potassium niobate KNbO3 crystal, with a significant deamplification of
about -3dB. The quantum noise of each individual pulse is registered in the
time domain using a single-shot homodyne detection operated with femtosecond
pulses and the best squeezed quadrature variance was measured to be 1.87 dB
below the shot noise level. Such a scheme provides the basic ressource for
time-resolved quantum communication protocols.
