Long-distance entanglement swapping with photons from separated sources

Published in Physical Review. A. 2005, vol. 71, no. 5
Abstract We report the experimental realization of entanglement swapping over long distances in optical fibers. Two photons separated by more than 2km of optical fibers are entangled, although they never directly interacted. We use two pairs of time-bin entangled qubits created in spatially separated sources and carried by photons at telecommunication wavelengths. A partial Bell-state measurement is performed with one photon from each pair, which projects the two remaining photons, formerly independent onto an entangled state. A visibility high enough to infer a violation of a Bell inequality is reported, after both photons have each traveled through 1.1km of optical fiber.
