Abstract :
We report background-free, near-infrared-to-telecom quantum frequency down-conversion, mediating two-photon interference with a mean wavepacket overlap larger than 0.89, regardless of the original separation between photon sources in wavelength (900- and 911-nm), wavepacket, and distance (2 km).
