Course objectives

Luminescent defects in wide band gap materials are promising candidates for technological applications based on photonics and provide a viable path towards the practical realization of quantum devices. This course provides an introduction to the current trends in experimental quantum
optics and material science, based on the fabrication and exploitation of single-photon sources for quantum information processing and quantum sensing.
