Abstract :
We demonstrate a new technique of efficient, time-resolved, infrared single-photon detection using non collinearly phase-matched frequency upconversion by an ultrafast pump, allowing nearly background-free sub-picosecond characterization of 1582-nm time anti-correlated entangled photons.
