Abstract
We demonstrate high-quality distribution of polarization-entangled photons generated from a fiber-coupled periodically poled waveguide over fiber-optic cables. Time-multiplexed measurements with a 19% efficient superconducting nanowire single-photon detector at the remote location show a detected flux of at a pump power of and an average two-photon quantum-interference visibility of 97.7% without subtraction of accidentals.
