France’s Quantum Sector Focuses on Manufacturing and Integration

In September 2026, France focused on the foundational elements of the quantum stack—those critical components that, while not always newsworthy, are essential for bringing technology to market. Companies announced chip results from commercial semiconductor lines, finalized testing and cooling agreements, and published architectural designs for integrating quantum processors with conventional computing. 

The French National Quantum Update for September 2026 from The Quantum Insider documented the month’s activities across research, business, and defense.

The crucial question is not whether France has secured funding: it has. Instead, the question is whether companies like Quobly, Alice & Bob, Pasqal, and Quandela, along with the nation’s defense programs, can translate public investment into functional hardware and successful deployments before other national programs advance further.

The Funding Context for the Year

The September activities are set against a significant funding commitment made earlier in 2026. On May 22, 2026, President Emmanuel Macron announced an additional €1.55 billion under France 2030, allocating €1 billion to quantum technologies and €550 million to semiconductor research and industrialization, as reported by The Quantum Insider. Quantum Computing Report estimated the quantum portion at approximately $1.16 billion, noting it as an addition to the existing national quantum plan.

A quick note of caution: the precise budget allocations, named beneficiaries, and disbursement timelines have not yet been officially released in France 2030 documentation. Therefore, the reported figures should be considered preliminary until confirmed. It’s also important to distinguish the €1 billion quantum allocation from the €550 million semiconductor allocation, as they fund different initiatives.

Manufacturing: Quobly on a Commercial Silicon Line

Quobly’s September results provide the clearest indication of manufacturing progress. The company reported successful qubit readout, single-qubit gates, and two-qubit gates on chips utilizing its QSOI technology. These chips were fabricated at STMicroelectronics’ commercial 300 mm facilities in Crolles, near Grenoble. This represents a measured outcome from devices produced through an industrial process, not merely a projection.

Quobly characterized this as an initial validation of a path toward repeatable, scalable processor manufacturing. The company also expanded its collaboration with CEA-Leti, gaining access to the FAMES Pilot Line to test process flows for future processor generations. Though qubit counts, error rates, and deployment timelines were not disclosed, the demonstration serves as a proof of fabrication rather than a performance claim.

Two additional agreements supported these developments:

• A memorandum of understanding with Orange Quantum Systems, based in Delft, to conduct large-scale testing of silicon spin-qubit devices.
• An industrial partnership with Absolut System for cooling systems, following a milestone in the QCube 100-Class 3 cryogenic program, which is linked to Quobly’s Alloy product family.

Software: Connecting Quantum to Existing Machines

Another key theme was the integration of quantum with classical computing. CEA and Alice & Bob announced their collaboration to develop software that links quantum processors with conventional supercomputers. They argued that the industry should avoid the single-ecosystem dependency that solidified NVIDIA’s dominance in AI, as reported by Reuters. This argument is particularly noteworthy given other developments that month.

Quandela published a white paper detailing how its photonic QPU would integrate into NVIDIA infrastructure. In this setup, the CPU would manage workflows, the GPU would handle AI computations, and the quantum processor would serve as a specialized accelerator for specific workloads. This integration approach is not unique to France. For instance, Xanadu and Bluefors announced their own cryogenic infrastructure development for utility-scale quantum systems, highlighting the current focus on foundational “plumbing” rather than just qubits.

Pasqal reported €4.9 million in first-half 2026 revenue, a 14% year-over-year increase, with QPU-related services growing 34% to €3.9 million. The company also reported an operating loss of €59.2 million, a cash balance of €110.8 million, along with 1,024-atom registers and CUDA-Q integration.

Defense Work Advances, One Company Shifts Focus

France’s defense-related quantum initiatives continued to progress, though with a change in participants. Thales, Bull, and CEA committed to a five-year project on Aliquante, a software platform designed for programming future French quantum machines in classified environments. C12 and Thales unveiled QuantumTrack, a hybrid quantum-classical method for radar target tracking, which earned a 2026 Quantum Effects Award.

Meanwhile, Pasqal announced its withdrawal from LSQUARE, also known as PROQCIMA. This Ministry of the Armed Forces program aims to develop two domestically designed universal quantum computer prototypes for industrialization by 2032. Pasqal stated it had achieved its first-phase objectives and would now redirect its public-sector efforts toward commercial applications. Alice & Bob remains a participant in this defense initiative, and France previously acquired a cat-qubit machine through GENCI. Details on the current PROQCIMA milestone status and the full participant list were not provided here.

Why Semiconductors Share the Same Funding Package

The €550 million semiconductor allocation is not a minor detail. Quobly’s reliance on STMicroelectronics for fabrication underscores why France has paired chip funding with quantum funding. Quantum hardware built on silicon leverages the same manufacturing infrastructure that supports the nation’s broader chip and AI ambitions. Other governments are establishing similar connections, from Virginia’s new quantum hub at George Mason to software initiatives like Fujitsu open-sourcing a quantum application package.

However, cross-border supply chains add complexity. September’s agreements alone involved entities in the Netherlands, the United States, Vietnam, Canada, and South Korea, with Quandela reportedly exploring chip manufacturing with Samsung and SK Hynix. This dynamic creates a tension between sovereign funding goals and the realities of international supply chains.

What to Watch Through Late 2026 and 2027

• The disbursement of the €1 billion quantum allocation, including named recipients and project scopes.
• Progress on PROQCIMA prototypes and the updated participant list following Pasqal’s departure.
• Technical disclosures from Quobly and Alice & Bob, particularly concerning qubit counts and error rates.
• Specific details on semiconductor funding tied to AI and data center buildouts.
• Any French policy developments regarding post-quantum cryptography or secure communications, which were not covered in the provided reporting.

France has secured the necessary funding and boasts a growing ecosystem of companies dedicated to quantum development. September’s focus on manufacturing lines, cooling systems, and software integration, rather than solely on qubit records, demonstrates this commitment. The critical question moving forward is whether these efforts will translate into deployable systems within a competitive timeframe.
