    "abstract": "Sources of entangled photon pairs using two parametric down-converters are\ncapable of generating interchangeable entanglement in two different degrees of\nfreedom. The connection between these two degrees of freedom allows the control\nof the entanglement properties of one, by acting on the other degree of\nfreedom. We demonstrate experimentally, the quantum distillation of the\nposition entanglement using polarization analyzers.",
