    "abstract": "We report on the generation of non separable beams produced via the\ninteraction of a linearly polarized beam with a cloud of cold cesium atoms\nplaced in an optical cavity. We convert the squeezing of the two linear\npolarization modes into quadrature entanglement and show how to find out the\nbest entanglement generated in a two-mode system using the inseparability\ncriterion for continuous variable [Duan et al., Phys. Rev. Lett. 84, 2722\n(2000)]. We verify this method experimentally with a direct measurement of the\ninseparability using two homodyne detections. We then map this entanglement\ninto a polarization basis and achieve polarization entanglement.",
