Applications of quantum photonics to quantum communications and quantum simulation or computing require a scalable, compact and low-cost technology for future widespread deployment. Researchers at SiNaPS and NPSC have recently observed the enhancement of the spontaneous emission of implantation defects in a silicon-based optical microcavity. This is a major step toward efficient single photon sources on silicon chips, based on an isolated color center in a cavity.
Applications of quantum photonics to quantum communications and quantum simulation or computing require a scalable, compact and low-cost technology for future widespread deployment. The silicon-on-insulator (SOI) platform is highly attractive in this context, offering the possibility to implement a large panel of integrated devices for the coherent manipulation, encoding and detection of single photons. However, the lack of a source able to emit a single photon pulse on demand increases the complexity and limits the performances of quantum photonic chips.
