    "abstract": "We present a setup to perform sub shot noise measurements of the phase\nquadrature for intense pulsed light without the use of a separate local\noscillator. A Mach--Zehnder interferometer with an unbalanced arm length is\nused to detect the fluctuations of the phase quadrature at a single side band\nfrequency. Using this setup, the non--separability of a pair of quadrature\nentangled beams is demonstrated experimentally.",
