    "abstract": "We produce polarization entangled states with variable degree of entanglement\nfor twin photons. Entanglement in polarization is coupled to entanglement in\nposition that produces transverse coincidence interference fringes. We show\nboth theoretically and experimentally that, due to this coupling, we can use\nthe interference pattern to measure the polarization degree of entanglement.",
