Abstract

© 2016 American Physical Society. We demonstrate quantum logic using narrow linewidth photons that are produced with an a priori nonprobabilistic scheme from a single Rb87 atom strongly coupled to a high-finesse cavity. We use a controlled-not gate integrated into a photonic chip to entangle these photons, and we observe nonclassical correlations between photon detection events separated by periods exceeding the travel time across the chip by 3 orders of magnitude. This enables quantum technology that will use the properties of both narrow-band single photon sources and integrated quantum photonics.
