Quobly, a Grenoble company that builds quantum computers on silicon, announced a €115m (about $133.6m) Series A on 3 June 2026. Bpifrance, SEALSQ and STMicroelectronics led the round, according to Quobly's announcement and Tech.eu.
New investors included the European Innovation Council's EIC Fund, Blast and ALIAD, the venture arm of Air Liquide. Existing investor Innovacom also took part. Existing shareholders named in the announcement are CEA, CNRS, Quantonation and Supernova Invest. No valuation was disclosed.
Bpifrance invested through its Deep Tech 2030 fund, which it manages on behalf of the French government under the France 2030 programme.

A note on the amount
Some early syndicated versions of a SEALSQ announcement described the round as €130m. SEALSQ's current release, Quobly's own announcement and Tech.eu all give €115m, so that figure is used here. SEALSQ said it invested as a lead investor through its SEALSQ Quantum Fund, which it says has grown to $200m, and did not disclose the size of its own cheque.
What Quobly does
Quobly says it brings semiconductor-grade manufacturing and industrialisation to quantum computing. Its machines store quantum information in silicon, so they can in principle be built with chip-industry processes. Its product line is called Alloy.
Tech.eu reported that the first system, Alloy Pioneer, is expected on the cloud in 2026 through Alloy Forge, and later in high-performance computing environments. Quobly's announcement says the first commercial quantum computer will be deployed through the cloud by the end of 2026.
Maud Vinet is chief executive and co-founder. In the announcement she said the Series A marks a shift from technology validation to industrial deployment.
What the money is for
Quobly said it will use the money for continued research and development, industrialisation of its silicon quantum processors, and international commercial expansion. Tech.eu listed work to improve the performance and scalability of the platform, development of hardware, control electronics and the software stack, and deployment of the first Alloy systems in cloud and HPC settings.
Carlos Moreira, chairman and chief executive of SEALSQ, said: "SEALSQ's participation as a lead investor in Quobly's Series A financing represents a significant milestone." Vinet said trusted semiconductor technologies and secure computing environments will become increasingly important for real-world adoption.
The funding so far
Tech.eu said the Series A followed a seed phase but gave no amount, date or investors for it. The sources opened for this article do not report total funding or headcount, and do not name customers, so none are stated.
Quobly has not yet put a commercial machine into customers' hands. The next milestone named in the sources is the delivery of the first Alloy system on the cloud by the end of 2026, followed by deployment in high-performance computing environments. The company's announcement also lists international commercial expansion among its uses of the funds, without naming target countries or customers.
