Nanophotonics for quantum technologies

Recent experimental advances in the integration of quantum emitters with nanophotonic structures opens up unprecedented for quantum technologies [1]. In particular, the low dimensionality of the photons enables to obtain longer ranged interactions than with free-space setups that can be harnessed for quantum simulation purposes [2], as well as for improving the figures of merit of non-classical light-generation [3]. Besides, the possibility to engineer topologically non-trivial photonic band structures [4] opens the realization of topological light-matter interfaces [5], opening a path to engineer robust quantum devices based on such effects [6]. In this talk, I will review some of my main contributions to this field [2,3,6].
