Title High-quality fiber-optic polarization entanglement distribution at 1.3 μm telecom wavelength Type Journal Article
Year 2010 Publication Optics Letters Abbreviated Journal Opt. Lett.
Volume 35 Issue 9 Pages 1392-1394
Keywords
Abstract We demonstrate high-quality distribution of 1.3 μm polarization-entangled photons generated from a fiber-coupled periodically poled KTiOPO4 waveguide over 200 m fiber-optic cables. Time-multiplexed measurements with a 19% efficient superconducting nanowire single-photon detector at the remote location show a detected flux of 5.8 pairs / s at a pump power of 25 μW and an average two-photon quantum-interference visibility of 97.7% without subtraction of accidentals.
