The FranceQCI project, co-funded by the European Union, lays the foundations of a future French quantum communications infrastructure (QCI), as part of a future EuroQCI, with an interface to existing terrestrial communication networks. <br />This is to protect against threats from overpowered quantum computers able to break the classical asymmetric encryption. <br />FranceQCI brings together Orange (pilot), Thalès, Airbus, start-ups, research laboratories and DSNA (french Air Navigation) as an institutional end user. <br />DSNA thus participated in an exercise in 2025 in its innovation premises in Toulouse (Technical Department, DTI), with its use-case and its needs that are different from those of the banking or defense sector.
