Thales Alenia Space has signed a contract with the European Space Agency (ESA) to lead the TeQuantS project aimed at developing quantum space-to-Earth communications technologies. This contract, part of ESA’s ARTES 4.0 Core Competitiveness programme element, is supported by the French space agency CNES (Centre National d’Etudes Spatiales) and Austrian space agency ALR.

The TeQuantS project intends to develop quantum technologies for cybersecurity applications and future quantum information networks. These technologies will enable Thales Alenia Space and its partners to build satellites and optical ground stations by the end of 2026. TeQuantS will thus help to demonstrate the performance of long-distance quantum satellite links.

The main cybersecurity challenge is to generate secure cryptographic keys using the quantum properties of light and distribute them to users anywhere in the world. This capability is a response to the threat of quantum computers potentially able to crack cryptographic keys now in daily use.

The key challenge for quantum information networks is to enable future quantum computers and sensors to talk to each other and fulfill their promised exponential gains in performance.

Quantum communications are currently the focus of major research and development programmes, notably the EuroQCI project in Europe.

The TeQuantS project led by Thales Alenia Space will draw on the expertise of a consortium composed of fellow prime Airbus Defence and Space, seven smaller firms and startups (ALPAO, AUREA Technology, BERTIN Technologies, MIRATLAS, OGS Technologies, QTlabs and SIGMAWORKS), and two research laboratories (LIP6 – Sorbonne University and INPHYNI – Côte d’Azur University/CNRS). The project partners will be innovating together to advance quantum communications in pursuit of Europe’s objectives.

Commenting on the deal, Javier Benedicto, Acting Director of Telecommunications and Integrated Applications at ESA, said: “Supporting European autonomy, leadership and responsibility in today’s digital world is becoming increasingly important. We are proud to be working with the consortium led by Thales Alenia Space to ensure that European citizens will continue to benefit from space-based secure connectivity in everyday life on Earth.”

Marc-Henri Serre, Thales Alenia Space Executive Vice President, Telecommunications, added: “We’re delighted to be working with our partners to develop quantum technologies that will demonstrate the ability to establish operational long-distance satellite quantum communications links and support Europe’s sovereignty in this area. We thank ESA, CNES and the Austrian Space Agency for their vital support on this project, which is addressing future cybersecurity and quantum information network challenges.”
