In article number 1705450 , Francesco Biccari and co‐workers describe a novel and versatile approach for the post‐growth fabrication of site‐controlled, single‐photon‐emitting quantum dots. This approach, which deploys the hot spot of a near‐field microscope to locally remove hydrogen from nanometer‐sized regions of a standard GaAs/GaAsN:H/GaAs quantum well, features state‐of‐the‐art control over both the nanostructure position (<100 nm) and emission energy (≈20 meV).
