    "abstract": "We report the first direct experimental characterization of continuous\nvariable quantum Stokes parameters. We generate a continuous wave light beam\nwith more than 3 dB of simultaneous squeezing in three of the four Stokes\nparameters. The polarization squeezed beam is produced by mixing two quadrature\nsqueezed beams on a polarizing beam splitter. Depending on the squeezed\nquadrature of these two beams the quantum uncertainty volume on the\nPoincar\\\u0027{e} sphere became a `cigar\u0027 or `pancake\u0027-like ellipsoid.",
