Ultratunable quantum frequency conversion in photonic crystal fiber

Abstract

Quantum frequency conversion of single photons between wavelength bands is a key enabler to realizing widespread quantum networks. We demonstrate the quantum frequency conversion of a heralded 1551 nm photon to any wavelength within an ultrabroad (1226 - 1408 nm) range in a group-velocity-symmetric photonic crystal fiber (PCF), covering over 150 independent frequency bins. The target wavelength is controlled by tuning only a single pump laser wavelength. We find internal, and total, conversion efficiencies of 12(1)% and 1.4(2)%, respectively. For the case of converting 1551 nm to 1300 nm we measure a heralded $g^{(2)}(0)=0.25(6)$ for converted light from an input with $g^{(2)}(0)=0.034(8)$. We expect that this PCF can be used for a myriad of quantum networking tasks.
