Abstract
We demonstrate high-quality distribution of 1.3 mu m polarization-entangled photons generated from a fiber-coupled periodically poled KTiOPO[subscript 4] 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 muW and an average two-photon quantum-interference visibility of 97.7% without subtraction of accidentals.
