# Quobly's €115M Series A: France Bets on Silicon-Based Quantum

> French quantum startup Quobly raised €115M Series A in June 2026 to industrialize silicon-based quantum processors compatible with existing semiconductor fabs.

Quobly's **€115M Series A** in June 2026 is one of Europe's largest quantum Series A rounds — and a distinctly French bet: build quantum processors on **silicon**, leveraging the existing semiconductor supply chain.

### The problem this startup is attacking
Most quantum approaches require exotic materials and bespoke fabrication. Quobly's silicon-based qubits aim to ride existing chip-manufacturing infrastructure, a potential shortcut to industrial scale.

### Why this is a live problem now
- Manufacturability — not just qubit counts — is the bottleneck to useful quantum.
- Europe wants sovereign quantum capability.
- Silicon compatibility could compress the path to commercialization.

### Competitive map
- **Oxford Quantum Circuits**, **IQM**, **Pasqal** (European peers).
- Silicon-spin-qubit efforts globally (Intel, others).
- Superconducting and trapped-ion approaches.

### Market signal (the number to remember)
- **€115M Series A** — sizable early-stage conviction in a manufacturing-first quantum thesis, with a stated goal of a first commercial system.

### Practical takeaway (operator + investor)
Quobly reinforces that quantum's winners may be decided by **fab compatibility and supply chain**, not lab benchmarks alone. Founders should emphasize manufacturability; investors should weigh the long horizon against the strategic upside.
