Description
We describe our progress in developing a proof-of-principle hybrid quantum repeater based on laser-cooled caesium ensembles and a semiconductor quantum dot. The atoms here can be used as a quantum memory or as a non-linear medium whilst the quantum dot can be used as a bright source of entangled photon pairs. The laser cooled atoms are loaded inside a hollow-core fiber to achieve an optical depth $\sim$1000. This has the potential to enable strong interactions with photons emitted by the quantum dot, which have bandwidth of $\sim$1 GHz and can be tuned to match the cesium D$_1$ line. The atoms confined in the hollow-core fiber can be used to store single photons from the quantum dot and to realize single-photon wavelength conversions for quantum key distribution (QKD) via ground-to-satellite or telecom-fiber links.
