Airbus and SES have signed a ground lease agreement with the Dutch municipality of Noordwijk, beginning construction of a new optical ground station at the NL Space Campus on July 15, 2026. The facility will be the primary ground connection for EAGLE-1, Europe’s first satellite dedicated to demonstrating end-to-end ultra-secure communication based on quantum technology, managed in partnership with ESA and the European Commission. To maintain a precise laser link with the satellite, the station will utilize advanced optics to correct real-time atmospheric distortions caused by turbulence. Xavier Bertran, SES’ Chief Product and Innovation Officer, stated that the optical ground station will be the primary ground connection for the EAGLE-1 system, promising early adoption of quantum-safe technology for sectors like government and banking.

A ground lease agreement, signed on July 15, 2026, between SES, Airbus, and the Dutch municipality, will facilitate construction of the facility designed to receive quantum keys transmitted via laser technology. EAGLE-1 represents a major advancement in developing a European system for Quantum Key Distribution (QKD), moving beyond radio frequencies to utilize laser beams for secure long-distance connections; it is not simply an upgrade to existing satellite communication. Airbus will construct the station for SES, incorporating a control room and a dome housing an ultra-precise telescope essential for maintaining the laser link with the EAGLE-1 satellite. The project’s technical implementation draws upon a network of specialized partners, with TNO serving as the prime contractor and responsible for the advanced optics, FSO Instruments delivering the sensor, and Airbus Netherlands providing the real-time control system. Officina Stellare is contributing the telescope and dome, and Celestia STS is responsible for the optical digital modem.

The optical ground station will serve as the primary ground connection for the EAGLE-1 system managed by SES in a public-private partnership with ESA and the European Commission (EC). Once operational, the system will allow early adoption of the quantum-safe technology by users such as government and banking sector, enabling next-generation cybersecurity.

This facility, situated adjacent to ESA’s ESTeC technical center, will be the crucial terrestrial link for the EAGLE-1 satellite, Europe’s inaugural demonstration platform for end-to-end ultra-secure quantum communication. Airbus is undertaking the construction of the station for SES, integrating a control room with a specialized dome designed to house an ultra-precise telescope. Maintaining a stable connection is paramount, and the station will employ advanced optics to counteract atmospheric distortions, specifically turbulence caused by air movement and temperature fluctuations. Unlike conventional satellite links, EAGLE-1 utilizes laser beams for transmitting security keys, offering an enhanced level of security for long-distance communication.

Ivy Delaney has been working with neural networks and machine learning since the mid-nineties, back when a couple of hidden layers and a long afternoon of training counted as ambitious. She has watched the field go from academic curiosity to the thing quietly running underneath everything, and she brings that long view to quantum computing. For Quantum Zeitgeist she covers the ground where the two fields meet. That means quantum machine learning and the variational algorithms it leans on, and it also means the less glamorous but more interesting story of classical machine learning already doing real work inside quantum machines, decoding error-correcting codes, calibrating noisy hardware and learning the error models that simulators depend on. She writes about the hardware those algorithms have to run on too, and about the post-quantum cryptography scramble that the same hardware has set off. Her stories typically start with the paper, whether that is peer-reviewed work, conference proceedings or an arXiv preprint, with the source linked so you can hold a claim up against the research it came from. She is unimpressed by benchmarks that will not say what they beat, and by demonstrations that only work in the press release.
