European Space Agency

The European Space Agency is an intergovernmental organisation rather than a commercial company, established in 1975 and headquartered in Paris, with 22 member states plus associate members. Its quantum work centres on space-based quantum key distribution and secure optical communications, including the approved SAGA satellite mission, and on cold-atom quantum sensors such as atomic clocks and atom interferometers for navigation, timing and Earth observation. It funds and coordinates research through member-state contracts and industrial consortia rather than developing quantum hardware as a commercial product line.

European Space Agency target met, a gigahertz of entangled photons

Covesion has reported a polarization-entangled photon-pair source at 1560 nm that exceeds a 1 GHz generation rate, meeting a target set by the European Space Agency. The result addresses a key performance requirement for high-rate quantum key distribution and quantum information processing.

OutlookPlausible

This could accelerate space-based QKD by enabling low-Earth-orbit satellites to distribute secret keys at rates high enough for continuous encrypted links, provided the source survives launch and space qualification.
