| Abstract: | I will present a hybrid quantum system that we developed by bridging two fields of physics: semiconductors and atomic physics [1]. Our system consists of a single artificial atom (semiconductor part) and natural atoms (atomic part), and combines the key advantages of both constituents. Using this system we have developed a universal source of indistinguishable single-photons, by frequency-locking an artificial atom to natural atoms [2]. Further, we have demonstrated non-classical light storage, where single photons are generated form an artificial atom and then stored in a vapor of natural atoms. I will also present crystal-phase quantum dots that we discovered in nanowires. They are now a novel degree of freedom in device design at the nanoscale, with exceptional crystallographic and optical properties. [1] N. Akopian et al., Nature Photonics 5, 230 (2011). [2] N.
