For tomorrow’s quantum technologies: hexagonal boron nitride under the magnifying glass / findings published in -Optica-

Quantum technologies are a seminal field of research, especially in relation to their application in communication and computing. In particular, the so-called single-photon emitters - materials that emit single light quanta in quick sequence - are an important building block for such applications. Photons are an excellent means of transmitting data in a fast and secure manner. However, it is necessary to have a sound physical understanding of the structure of the single-photon emitter and how to control them. ...
