Description:
Author(s): Florian Wolfgramm, Yannick A. de Icaza Astiz, Federica A. Beduini, Alessandro Cerè, and Morgan W. Mitchell We demonstrate the generation of rubidium-resonant heralded single photons for quantum memories. Photon pairs are created by cavity-enhanced down-conversion and narrowed in bandwidth to 7 MHz with a novel atom-based filter operating by “interaction-free measurement” principles. At least 94% of ... [Phys. Rev. Lett. 106, 053602] Published Tue Feb 01, 2011
