Colloque - Anaïs Dréau : Single Color Centers for Silicon-Based Quantum Technologies

About this episode

Anaïs Dréau discusses the potential of single color centers in silicon for advancing quantum technologies.

Pascale Senellart Chaire annuelle Innovation technologique Liliane Bettencourt (2025-2026) Collège de France Année 2025-2026 Colloque : Light-based Quantum Technologies Pascale Senellart, chaire Innovation technologique Liliane Bettencourt Colloque - Anaïs Dréau : Single Color Centers for Silicon-Based Quantum Technologies Anaïs Dréau Résumé Capitalizing on the success of the microelectronics and integrated photonics industries, silicon is the material that has generated the most scientific interest for quantum technologies and offers currently the greatest diversity of integrated quantum systems. 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.
