Traditionally, Quantum Optics is a field of research investigating light, matter and its interactions. In this talk, I will discuss several instances were methods and ideas from Quantum Optics find novel counterparts in solid-state nanostructures: By identifying photons with electrons, and atoms with nuclear spins, we show that the build-up and reinforcement of correlations among nuclear spins can give rise to the new phenomenon of electronic superradiance in the current through a single quantum dot. Building upon the same analogy, we show how to entangle dissipatively two nuclear spin ensembles in a double quantum dot, without requiring any unitary gates. Lastly, by identifying the role of photons with phonons based on surface acoustic waves, in analogy to cavity QED we propose a universal, scalable, on-chip quantum information architecture in piezo-active materials.
