Quobly Lands €115M to Industrialise Silicon Quantum

The big picture: Quobly, a Grenoble-based quantum computing company, closed a €115 million Series A financing round to accelerate the industrialisation of its silicon-based quantum computers and launch its first commercial product by the end of 2026.

Why it matters:

• Industrialisation Focus: This funding marks a critical transition for Quobly from technology validation to industrial execution, aiming to deliver deployable and scalable quantum computing solutions for real-world industrial environments.
• Strategic Investor Backing: The round was led by key players like Bpifrance, SEALSQ, and STMicroelectronics, alongside participation from the European Innovation Council (EIC), Blast, Air Liquide Venture Capital (ALIAD), and existing investor Innovacom, signaling strong confidence in Quobly’s approach.
• Market Entry Timeline: Quobly plans to launch its first commercial product, Alloy Pioneer, by late 2026, making silicon-based quantum computing accessible via the cloud and integrated into high-performance computing (HPC) infrastructures by 2027.

How it works:

• Silicon-Based Qubits: Quobly develops quantum computers utilizing silicon-based qubits, leveraging established semiconductor manufacturing processes, specifically Fully Depleted Silicon On Insulator (FD-SOI) technology on 300 mm wafers.
• Ecosystem Integration: The company collaborates with industrial leaders such as STMicroelectronics, Air Liquide, Soitec, and Orano to integrate process control, materials engineering, cryogenics, and yield optimization from the earliest stages of deployment.
• HPC Compatibility: Quobly’s quantum computers are engineered for seamless integration into existing HPC and data center infrastructures, designed with compatible footprint, power supply, and utility requirements for straightforward deployment.

The catch: The quantum computing market is highly competitive, with numerous startups and tech giants (IBM, Google, Microsoft) investing heavily in various qubit technologies. While silicon-based qubits offer advantages in manufacturability and scalability due to their compatibility with existing semiconductor infrastructure, achieving fault-tolerant quantum computing remains a significant engineering challenge. Quobly’s success hinges on its ability to rapidly scale qubit count and maintain coherence in a noisy environment, while also demonstrating clear performance advantages over classical supercomputers for specific, high-value problems. The timeline for widespread commercial adoption of quantum computing is still uncertain, and the company will face pressure to deliver tangible results beyond research applications.
