Recently, in 2020, a new type of physical systems in silicon has emerged for quantum applications: individual color centers. These fluorescent point defects can be isolated at single defect-scale using low-temperature confocal microscopy, and emit single photons directly at telecom wavelengths, suitable for long-distance propagations in optical fibers. Furthermore, some of these defects are also coupled to an optically detectable electron spin that could be used to store and process quantum information.
