Colour centres, also known as solid state defects, and most closely associated with the diamond NV centre, are used for a wide range of quantum applications. Researchers have studied their use for single photon sources, quantum memories, quantum repeaters, and for a variety of quantum sensing applications, including piezometers, electrometers, thermometers, and magnetometers1.
Colour centres have several advantages as compared to other systems, including relatively long coherence time, operational temperatures up to room temperature, a variety of optical operational frequencies, and all the advantages inherent to any solid-state system, such as compatibility with well-developed tools for lithography, etch, and thin film deposition.
