Isolation of individual Er quantum emitters in anatase TiO2 on Si photonics.
Appl. Phys. Lett. 125, 084001 (2024) Defects and dopant atoms in solid state materials are a promising platform for realizing single photon sources and quantum memories, which are the basic building blocks of quantum repeaters needed for long distance quantum networks. In particular, trivalent erbium (Er3+) is of interest because it couples C-band telecom optical transitions […]
