Photonic quantum technology is creating breakthroughs in both fundamental quantum science and applications such as quantum communication, computation and sensing. Regarded as artificial atoms due to the discrete energy levels they support, semiconductor quantum dots serve as a core element in emerging modern photonic quantum technologies, allowing on-demand generation of single-photons and entangled photon pairs. This review article focuses on the enabling technologies developed for reliably accessing the properties of QDs as atom-like entities in the solid state.
