Oxford Quantum Circuits provides Quantum Computing as a Service (QCaaS) using superconducting qubits built on its Coaxmon architecture. Clients access quantum hardware through direct access, managed services, cloud platforms, or colocated data centers, enabling hosted computations and managed workflows without building their own systems. The company differentiates itself with its Coaxmon qubit design, enterprise focus, and its status as the UK’s first QCaaS platform, backed by significant funding and global expansion. Its goal is to broaden enterprise access to quantum computing to tackle complex problems in areas like climate modeling and AI, and to scale a global quantum hardware and services ecosystem.

Simplify's Take
What believers are saying
- June 2026 funding supports Barcelona manufacturing and global QCaaS expansion.
- OQC’s 2026 waifer-scale 500-plus-qubit packaging demo strengthens technical credibility.
- New York, Tokyo, London, and Barcelona footprints widen enterprise and government sales reach.
What critics are saying
- OQC still sells 32-qubit systems while rivals chase larger fault-tolerant roadmaps.
- Quantum revenue depends on a tiny customer base; JPMorganChase concentrates near-term validation.
- If 500-plus-qubit packaging slips, OQC becomes a capital-intensive hardware lab, not a platform.
What makes Oxford Quantum Circuits unique
- OQC’s Coaxmon superconducting architecture targets scalable, fabless quantum hardware.
- June 2026 Series C makes OQC Europe’s best-capitalized private quantum hardware company.
- JPMorganChase, AMD, and OQC launched a secure London quantum-AI platform.

↓ -3%Quantum computing firm OQC has completed a £260 million Series C funding round, positioning itself as one of the best-capitalised private quantum computing companies globally. Chief executive Gerald Mullally said the capital will enable OQC to expand internationally and build secure, scalable quantum infrastructure for enterprise and government customers. Mullally noted that recent public market activity, including Quantinuum's initial public offering, is helping build investor confidence in the sector. He described the developments as signalling a shift for quantum computing beyond research towards practical infrastructure. The funding will support OQC's technology roadmap, advancing its quantum processors and software platforms. Mullally indicated the company's strategy includes shaping the industry's next phase through technological innovation and strategic partnerships.
Oxford Quantum Circuits (OQC), a British quantum computing startup, has raised £260 million (approximately €300 million) in a Series C round, marking Europe's largest private funding for a quantum computing company. The oversubscribed round was led by Bullhound Capital. Founded in the UK, OQC develops superconductor-based quantum computers for data centres serving enterprises and public administrations. The company has already deployed systems across Europe, North America and Asia, including installations in the UK, US, Japan and Spain. The funding will accelerate international expansion and development of fault-tolerant quantum computing technologies. OQC targets sectors including finance, defence and security, which require advanced computing capabilities for data processing, complex optimisation and enhanced analysis. CEO Gerald Mullally said the market is shifting from technological promises towards concrete deployments addressing real needs.
Oxford Quantum Circuits (OQC), JPMorganChase and AMD have announced a research collaboration centred on a new quantum AI data centre in London. JPMorganChase researchers will test quantum and hybrid quantum-classical computing applications in a secure enterprise environment to address complex financial services challenges. The collaboration aims to investigate how quantum-enhanced AI models can accelerate algorithm discovery for financial use cases. JPMorganChase will be the UK platform's first dedicated user, with full operations expected within 12 months. The platform integrates quantum hardware within a secure enterprise compute environment, enabling JPMorganChase to test hybrid workflows against financial services operational standards. This week, OQC closed an oversubscribed £260 million Series C funding round, Europe's largest private funding round for a quantum computing company.
Oxford Quantum Circuits has raised £260m ($350m) in a Series C round, marking the largest funding for a private quantum computing company in Europe. The round was led by Bullhound Capital, with participation from British Business Bank, European investors including Fynveur and Cofides, and US and Singapore-based firms. The UK-based scaleup builds quantum computers using superconducting qubits and offers them as a service through partner data centres in London, Tokyo and New York. Customers buy computing time rather than purchasing systems outright, an approach particularly attractive to regulated sectors like finance and defence requiring secure data storage. The funding will support geographic expansion and development of next-generation systems. OQC's current most advanced computer has 32 qubits, with CEO Gerald Mullally stating the goal is building systems for the "commercial era of quantum".
Oversubscribed Series C will scale OQC’s international footprint and deployed quantum infrastructure.
