    "abstract": "We generate and characterise continuous variable polarization entanglement\nbetween two optical beams. We first produce quadrature entanglement, and by\nperforming local operations we transform it into a polarization basis. We\nextend two entanglement criteria, the inseparability criteria proposed by Duan\n{\\it et al.}\\cite{Duan00} and the Einstein-Podolsky-Rosen paradox criteria\nproposed by Reid and Drummond\\cite{Reid88}, to Stokes operators; and use them\nto charactise the entanglement. Our results for the Einstein-Podolsky-Rosen\nparadox criteria are visualised in terms of uncertainty balls on the\nPoincar\\\u0027{e} sphere. We demonstrate theoretically that using two quadrature\nentangled pairs it is possible to entangle three orthogonal Stokes operators\nbetween a pair of beams, although with a bound $\\sqrt{3}$ times more stringent\nthan for the quadrature entanglement.",
