Under a program of and funded by the European Space Agency (ESA; http://www.esa.int/ESA), ID Quantique (Geneva, Switzerland) will supply high-reliability single-photon technologies to Ariane 6, the next generation of space launch vehicles built by ArianeGroup on behalf of the ESA. ArianeGroup is the prime contractor and design authority for Ariane 6.

The technologies developed under this Ariane 6 program require the highest level of performance and reliability, for which ID Quantique's single-photon systems have been selected: the ID280 single-photon detector, ID900 Time Controller with its OTDR package and ID300 Laser. ID Quantique says this collaboration reinforces its experience in the space sector and guarantees the long-term support of its products.
