Mid-2025: France Advances in Quantum Era
France made major advances in policy, industry, and research in July and August 2025, solidifying its quantum technology leadership. The quantum age affects many sectors of France life, from ambitious national programs and massive investment plans to groundbreaking scientific breakthroughs and developing international alliances. In computers, navigation, sensing, communications, and space, quantum technology is growing rapidly.

National Strategy: Quantum Future Security
In the face of geopolitical uncertainty, France is increasing its national defense ambitions and strengthening its commitment to disruptive technologies like artificial intelligence and quantum under President Emmanuel Macron. Fearing a lapse in these vital sectors, France’s defense budget is expected to increase dramatically from €50.5 billion in the present to €67 billion in 2030.
The administration has supported deeptech by strategic steps, including the creation of a Franco-British engineering facility with Imperial College and CNRS, which President Macron attended. The €54 billion France 2030 investment plan has not been affected by recent budget cuts, and a new space and quantum technology research program shows a sustained financial commitment.
Policymakers recognize the “quantum decade’s” rapid development on a larger European level. It has been warned, nevertheless, that even as hardware access improves, Europe could fall behind in the global race for quantum usefulness if it does not make significant investments in software development. In terms of France’s quantum strategy, this identifies a key area for future attention.
Businesses and Industries: Growing Capabilities and Partnerships
At the forefront of innovation, France quantum companies are proactively growing alliances throughout North America and Europe to develop solutions that are application-ready, scalable, and sovereign. During this time, important players have made significant progress:
One prominent player in photonic quantum computing in Europe is Quandela. Innovative quantum machine learning (QML) models are being developed by the firm in collaboration with Mila, the Quebec Artificial Intelligence Institute, to investigate hybrid AI and quantum computing technologies. Quandela is working on AI integration with NVIDIA and has previously sold quantum computers to customers in Europe. Additionally, Quandela is collaborating with attocube systems GmbH on the creation of the European quantum computer Lucy, signifying a strong demonstration of Franco-German cooperation.
As part of a pathway to quantum advantage, Pasqal and IBM have developed a formal methodology for identifying and proving when quantum computers can outperform classical systems in meaningful activities.
Leading quantum microelectronics company Quobly has partnered strategically with France’s national institute for digital science and technology research, Inria. By aligning silicon-based quantum hardware with cutting-edge control software, this partnership seeks to create a fully integrated, fault-tolerant, and scalable quantum computing architecture while also establishing a sovereign value chain.
Future medical diagnostics using quantum physics are being investigated in Thales facilities in Palaiseau, with the goal of creating gadgets that are as small as a pen and hundreds of times more accurate.
The France deeptech company HiQuTe Diamond was able to raise €7.5 million in order to industrialize the manufacturing of high-quality diamonds for use in next-generation sensors, power electronics, and quantum computing.
The acquisition of IC’ALPS was finalized by SEALSQ Corp, a semiconductor and post-quantum technology company, with final approval from the France Ministry of the Economy, Finance, and Industrial and Digital Sovereignty.
Leading fault-tolerant quantum computing company Alice & Bob and Inria have submitted a new article for peer review that describes the most hardware-efficient technique to date for creating “magic states” on superconducting quantum computers a critical step towards actual quantum computation.
During this time, quantum computing also had its “mainstream moment” as it came to the attention of the public and industry at VivaTech 2025, where NVIDIA CEO Jensen Huang served as emcee.

Pioneering Quantum Science Research
International recognition and new benchmarks are being set by France research, which keeps breaking new ground:
In a carbon nanotube circuit, a group of researchers comprising scientists from C12 Quantum Electronics and multiple France institutions reported a record-breaking 1.3 microseconds of coherence time. This is a significant improvement of 100 times over earlier carbon-based implementations and ten times over similar silicon quantum dot devices. Charge noise was found to be the primary cause of decoherence in a carbon nanotube gatemon qubit by a France-led team that also achieved record coherence times of 200 nanoseconds. These developments establish carbon nanotubes as viable options for upcoming quantum technology.
Researchers at École Polytechnique Fédérale de Lausanne (EPFL) have made significant advances in understanding topological quantum systems by developing a novel numerical method for simulating quantum spin liquids using Rydberg atoms.
Christopher Bäuerle’s ERC Advanced Grant 2024 for the development of novel quantum architectures and Igor Ferrier-Barbut’s CNRS Bronze Medal 2025 for his work storing and altering quantum information transported by light. France is a country that continues to foster scientific achievement.
Further enhancing France’s scientific standing was the election of Alain Aspect, the 2022 Nobel Prize in Physics recipient for his experimental work on quantum entanglement, to the esteemed Académie française.
Educational Events: Promoting Talent and Collaboration
A cooperative worldwide ecosystem is fostered by France, which is also a center for quantum education and events:
Attracting over 1,000 attendees and 60 foreign specialists, the France Quantum 2025 conference, held in June at Station F in Paris, was a significant international event. An “After Movie” that was released in July demonstrated how successful the conference was at bringing quantum technologies to a global audience.
Professor Anne Broadbent is leading a vibrant Canada-France partnership on nonlocal boxes that is expanding the frontiers of quantum research and providing students with life-changing international experiences.
In September 2025, Q2B Paris, Europe’s premier quantum conference, will bring together international experts, business executives, and lawmakers to align scientific advances with commercial and policy goals.
Finally, the mid-2025 updates suggest that France is exploring quantum technology’s immense potential. Strategic investments, innovative partnerships, and new research drive its leadership. These new technologies require software development, but the country is poised to lead Europe’s “quantum decade” ahead.
