Abstract

We demonstrate high-quality distribution of 1.3μm polarization-entangled photons generated from a fiber-coupled periodically poled KTiOPO4 waveguide over 200m 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 pairss at a pump power of 25μW and an average two-photon quantum-interference visibility of 97.7% without subtraction of accidentals.
