Quantum Distillation Of Position Entanglement With The Polarization Degrees Of Freedom
arXiv:quant-ph/0111065 · doi:10.1016/S0030-4018(02)01908-9
Abstract
Sources of entangled photon pairs using two parametric down-converters are capable of generating interchangeable entanglement in two different degrees of freedom. The connection between these two degrees of freedom allows the control of the entanglement properties of one, by acting on the other degree of freedom. We demonstrate experimentally, the quantum distillation of the position entanglement using polarization analyzers.
