IN Brief:
- Quobly has secured €115m to accelerate silicon-based quantum computing towards commercial availability.
- The company is using semiconductor manufacturing methods, including 300mm wafers and FD-SOI technology.
- The raise strengthens Europe’s push to turn quantum processing from laboratory hardware into scalable computing infrastructure.
Quobly has raised €115m in Series A funding to accelerate the commercial development of silicon-based quantum computers, bringing together public, strategic, and industrial investors behind a European hardware programme built around established semiconductor manufacturing methods.
The French company is developing quantum systems based on silicon qubits, with cloud access to its Alloy Pioneer system targeted by the end of 2026. Deployment into high-performance computing infrastructure is planned for 2027, giving the programme a defined route from hardware development into early commercial use rather than a purely research-led timeline.
The round includes backing from Bpifrance, SEALSQ, STMicroelectronics, the European Innovation Council Fund, Blast, ALIAD, and Innovacom, with existing shareholders including CEA, CNRS, Quantonation, and Supernova Invest. The funding will support work across qubit devices, control electronics, software integration, and the industrial engineering needed to move from demonstrators into repeatable systems.
Quobly’s use of 300mm wafers and FD-SOI technology gives its architecture a route into a manufacturing ecosystem already understood by the semiconductor industry. Quantum hardware still carries demanding constraints around cryogenic operation, qubit stability, error correction, readout, packaging, and system control, but compatibility with established silicon processes gives the company a more industrial scaling path than approaches built around highly bespoke device fabrication.
That manufacturing route places the programme close to wider European work on FD-SOI and secure chip production, including recent activity around CEA-Leti and GlobalFoundries’ FD-SOI development and European chip-flow work involving GlobalFoundries and Qualinx. In each case, the strategic direction is similar: specialist semiconductor capability is being pushed towards platforms with defensible industrial value rather than remaining as isolated process research.
Silicon quantum computing also changes the balance of engineering work. A quantum processor is not only a qubit array; it is a stack of signal delivery, control electronics, cryogenic integration, packaging, interconnect, software, calibration, and test. Scaling that stack requires repeatable devices and reliable control infrastructure, with tight attention to parasitics, noise, thermal loading, and manufacturability.
The funding arrives as quantum companies face a more demanding commercial environment. Investors and industrial partners increasingly want credible pathways to serviceable systems, not only laboratory milestones. Semiconductor compatibility gives Quobly a strong argument, although the decisive test will be whether process repeatability and system-level integration can support useful compute performance at scale.
Europe’s quantum ambitions are tied closely to that execution. The region has research strength, advanced laboratories, and established semiconductor assets, but the global competition is shifting towards industrialisation, packaging, control hardware, and supply-chain ownership. Quobly’s raise adds weight to the European side of that contest, particularly because the company is pursuing a route that could use existing chipmaking infrastructure more directly than several alternative quantum architectures.
If silicon qubits can be manufactured with sufficient yield and integrated with scalable electronics, quantum computing will move closer to the established semiconductor sector rather than remaining a separate scientific equipment market. Quobly’s new capital gives the company room to test that proposition against the unforgiving constraints of production hardware.
