  We report the experimental transformation of quadrature entanglement between
two optical beams into continuous variable polarization entanglement. We extend
the inseparability criterion proposed by Duan, et al. [Duan00] to polarization
states and use it to quantify the entanglement between the three Stokes
operators of the beams. We propose an extension to this scheme utilizing two
quadrature entangled pairs for which all three Stokes operators between a pair
of beams are entangled.
