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:
(i) 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 leakage current through a single quantum dot .
(ii) Building upon the same analogy, we show how to entangle two nuclear spin ensembles in the steady state, without requiring any unitary gates [2,3].
(iii) By identifying the role of photons with phonons based on surface acoustic waves, in analogy to cavity QED we propose a versatile, on-chip quantum information architecture in piezo-active materials .
