France launches Defence Quantum Campus to accelerate military technology integration

France has established a new Defence Quantum Campus designed to accelerate the adoption of quantum technologies across its military.

First announced in May and operational since June 1 in the suburbs of Paris, the campus serves as a centralized hub bringing together researchers, defense contractors, entrepreneurs, and investors.

“The core mission is to accelerate the operational deployment of quantum technologies within the armed forces,” Xavier Grison, General Armaments Engineer (IGA) and head of the campus, said in an interview with Euractiv.

Quantum technologies exploit the behavior of particles at atomic and subatomic scales, and are projected to transform fields ranging from computing and communications to sensing and navigation.

Defense-specific applications include post-quantum cryptography to secure communications against future quantum-enabled cyberattacks; advanced quantum sensors for GPS-independent navigation and enhanced detection; interception-resistant secure quantum communications; and quantum computing to rapidly simulate complex military scenarios, such as logistics, weapons systems performance, and weather forecasting.

The new campus operates with three primary objectives: strengthening ties with academic research, conducting in-house studies on defense-specific quantum use cases, and fostering closer relationships with industrial partners ranging from startups to major defense conglomerates.

A fourth pillar will focus on international cooperation.

France’s preferred partners in this technological domain will be countries within the European Union, which Grison described as the nation’s “natural circle of cooperation.”

Other nations, including Canada and Singapore, with which France already shares robust scientific and technological ties, will be evaluated on a case-by-case basis.

Grison noted that while the US remains an important partner, cooperation with Washington can prove more challenging.

“Preserving sovereignty and establishing a balanced partnership is more difficult,” Grison said, echoing broader European concerns regarding the maintenance of strategic autonomy in emerging technologies.

The campus will focus its efforts on three broad categories of quantum applications.

The most mature of these areas is quantum sensing, where systems are expected to significantly outperform conventional sensors.

“We have been working on this area for a very long time. We are confident that a portion of this research will yield concrete results,” Grison said.

Quantum computing represents the second major area of focus. While practical quantum computers capable of outperforming classical machines in useful tasks have yet to be proven, France maintains high expectations for the technology.

“We have identified five French companies utilizing five distinct technologies, all of which have a chance of success. The decision was made to mature all five. The goal is to reach a level of computational power by 2032 that surpasses even the most powerful conventional supercomputers.”

Grison identified quantum communication as the third category of focus for the campus, describing the field as currently being in a more “exploratory phase.”

Researchers hope that these systems will eventually overcome some of the physical limitations of traditional communication technologies, including those related to antenna usage.

For the Ministry of Armed Forces, the challenge lies not only in manufacturing hardware but also in developing software and identifying practical military applications.

Most of these potential applications will be dual-use in nature, offering utility to both the military and civilian sectors.

To help identify promising ideas, the campus has launched a “defense quantum hackathon” scheduled to take place in December.

A hackathon is an intensive innovation and coding marathon, typically lasting between 24 and 48 hours, in which software developers, designers, and subject-matter experts collaborate in teams to build innovative technical solutions to specific problems.

Participants in the event will receive training in quantum programming before being tasked with developing potential applications for the defense sector.

When asked what success would look like in ten years, Grison pointed to two key milestones: the emergence of a genuinely useful quantum computer and the deployment of an operational quantum sensor.
