III-V Lab has strong competences and established track record in R&D from advanced modeling to production in the field of III-V compound semiconductor (GaAs, InP, GaN …) and their integration on Si for applications such as RF and optical communications, lasers and infrared detection. Together with CEA-Leti they will realize these quantum devices act to constitute the quantum network. Their specific knowledge on integration of optics elements will enable the birth of transmitters and receivers which will be used for combining classical and quantum communication.
