Advancing Satellite-Based Quantum Communications with AUREA Technology

Quantum communication via terrestrial optical fiber networks is constrained to a few hundred kilometers due to fiber attenuation. For long-haul quantum communications and networking, satellite-based quantum communication is emerging as the most viable and scalable solution.

Since 2020, AUREA Technology has been at the forefront of developing key photonic building blocks for satellite-based quantum communication, collaborating on projects supported by the French Space Agency (CNES) and the European Space Agency (ESA).

The IQUPHOS project focuses on designing a multi-channel BBM92 entangled photon source and simulating its LEO (Low Earth Orbit) space-to-ground optical transmission. 

The TEQUANTS project aims to develop next-generation quantum technologies for future quantum networks. AUREA Technology is responsible for designing GHz single-photon counting detectors for Optical Ground Stations and developing a satellite-based entangled photon source.

Building on this expertise, AUREA Technology is now developing its first Elegant Breadboard (EBB) entangled-photon source, scheduled for delivery by the end of 2026. This milestone represents a major step toward compact, robust and space-compatible quantum photonic systems.

In parallel, the company is developing a “New Space” version of its near-infrared (NIR) single-photon detector, specifically designed for LiDAR applications aboard satellites in LEO. This technology aims to combine high detection performance with the reliability and compactness required for operation in space.

By pioneering space Quantum communications and networking, AUREA Technology is shaping the future of global quantum communication networks.
