Quobly Raises $125M to Build Silicon Quantum Computers

A French startup just landed a massive funding round to build quantum computers using the same kind of silicon chips found in your phone. Here's why that matters. ### The Big News: $125 Million Series A Quobly, a company spun out of two French research labs, just announced it closed a $125 million Series A financing round. The company is based in Grenoble, France, and it's on a mission to industrialize silicon-based quantum computers. The goal? Launch its first commercial product by the end of 2026. The round was led by Bpifrance, SEALSQ, and STMicroelectronics. Other big names jumped in too: the European Innovation Council (EIC), Blast, Air Liquide Venture Capital (ALIAD), and existing investor Innovacom. Current shareholders also include the CEA, CNRS, Quantonation, and Supernova Invest. ### What's the Big Deal About Silicon? Most quantum computing companies are chasing exotic materials. Quobly is taking a different path. They're using Fully Depleted Silicon On Insulator (FD-SOI) technology on 300 mm wafers. That's fancy talk for saying they're building quantum chips using the same manufacturing processes that already produce billions of chips for smartphones and computers. Why does that matter? Because the semiconductor industry has spent decades perfecting how to make silicon chips at scale. By piggybacking on that infrastructure, Quobly can skip years of process development. ### From Lab to Fab: The Industrial Strategy Maud Vinet, CEO and co-founder of Quobly, put it simply: "This financing marks a transition from technology validation to industrial execution." Her team has spent two years proving that silicon qubits can be built inside standard semiconductor fabs. Now they're moving to production. The company has partnered with industry giants like STMicroelectronics, Air Liquide, Soitec, and Orano to accelerate that transfer. ### The Product Roadmap: Alloy Pioneer Quobly's first commercial system is called Alloy Pioneer. It's part of their Alloy product line, designed for early adopters in high-performance computing (HPC) and research environments. Here's the timeline: - Cloud access in 2026 - Deployment inside HPC data centers in 2027 The system will be accessible through Alloy Forge, Quobly's quantum application development environment. That lets users build and test applications under realistic hardware constraints. ### Why This Approach Matters for Enterprise Here's what's clever: Quobly's quantum computers are designed to fit right into existing data centers. They match the footprint, power supply, and cooling requirements of standard HPC infrastructure. That means companies can deploy them without building special facilities. "Our objective is to make quantum computing deployable, scalable and usable within real industrial environments," Vinet said. ### The Bottom Line Quobly's industrial-first approach sets it apart. Instead of chasing breakthrough qubit counts, they're prioritizing manufacturability. They're co-developing technology and systems from day one. The company plans to use this funding to: - Increase performance and scalability of their quantum processors - Accelerate industrialization of silicon quantum processors - Deploy first Alloy systems into customer cloud and HPC environments - Expand hardware, control electronics, and software stack For the quantum computing market, this is a big step. It moves quantum from lab curiosity toward something that can actually be built and deployed at scale. And it's happening on the same silicon platform that already powers the digital world.
