    "abstract": "We have experimentally demonstrated polarization entanglement using\ncontinuous variables in an ultra-short pulsed laser system at telecommunication\nwavelengths. Exploiting the Kerr-nonlinearity of a glass fibre we generated a\npolarization squeezed pulse with S2 the only non-zero Stokes parameter thus S1\nand S3 being the conjugate pair. Polarization entanglement was generated by\ninterference of the polarization squeezed field with a vacuum on a 50:50 beam\nsplitter. The two resultant beams exhibit strong quantum noise correlations in\nS1 and S3. The sum noise signal of S3 was at the respective shot noise level\nand the difference noise signal of S1 fell 2.9dB below this value.",
