My research field combines quantum optics and material science at the nanoscale. We fabricate and investigate new devices for the generation, manipulation, and detection of single and entangled photons. I will discuss our approach to integrate bright deterministic sources of entangled photon-pairs in complex on-chip quantum circuits. We developed a hybrid nanofabrication technique, allowing to integrate III/V semiconductor nanowire quantum dots into silicon-based photonics. I will also briefly report on our efforts for long-range quantum communications using hybrid quantum network links, interfacing single-photons emitted from epitaxial quantum dots with a hot rubidium vapor quantum memory.
