Interfacing single photons from a quantum dot embedded in a semiconductor nanowire with a laser-cooled atomic ensemble confined to a hollow-core fiber

POSTER

Abstract

We report our experimental progress in interfacing single photons and entangled photon pairs emitted by a quantum dot embedded in an semiconductor nanowire with an ensemble of laser-cooled caesium atoms loaded into a hollow-core optical fiber. We explore controllable delays, wavelength conversion of single photons using a four-wave mixing process, and photon storage with the goal of creating a node for a quantum repeater.
