OQC has reached a major milestone in its mission to build the future of quantum computing.

We’re thrilled to announce the successful close of our £260 million Series C funding round – the largest fundraise ever completed by a quantum computing company in Europe. This milestone reflects growing confidence in the role quantum computing will play in shaping the future of the advanced computing industry and national capability.

This funding will support our global expansion, including scaling quantum infrastructure in key markets and advancing the development of our next-generation systems. It will deepen our research and development efforts, helping us accelerate innovation across both hardware and platform capabilities, while reinforcing our position as a global leader in the quantum computing field.

At OQC, our focus remains clear in building scalable, commercially quantum systems capable of delivering transformational performance.

This landmark investment reinforces the UK as the global hub for frontier innovation and deep technology, with OQC leading it’s capability.

Overview of the Raise

Our Series C round marks a defining moment for OQC and the wider quantum sector: reflecting the shift of quantum computing to scalable strategic infrastructure.

This oversubscribed round, led by Bullhound Capital, includes a strong combination of strategic and institutional investors, including British Business Bank, Oxford Science Enterprises, and Chevron, reflecting market confidence in OQC’s commercial trajectory, technological leadership and long-term market opportunity.

Quantum computing is one of the most transformational technologies of this century and, as demonstrated by the speed, accuracy and scalability of our roadmap, OQC is best  positioned to lead the market.

The Globally Leading Quantum Computing Company

At OQC, we develop and operate superconducting quantum computers engineered for real-world commercial and strategic applications, with deployments spanning the UK, US, Japan and Spain.

As Europe’s first Quantum-Compute-as-a-Service provider and the only company integrating quantum computers directly into commercial data centres, we are bringing enterprise-grade quantum capability into the heart of global digital infrastructure. With a growing international footprint and a roadmap focused on scalable, fault-tolerant systems, we are accelerating the transition of quantum computing from experimentation to real-world deployment. By combining world-leading engineering with commercial infrastructure integration, we are enabling practical quantum applications across major customer sectors.

”OQC’s £260 million funding round is a major vote of confidence in the UK’s quantum sector and shows that the UK continues to be the place where the industries of the future are being created.

We have the right economic plan and within it, I set out three 'big choices' for the UK economy - one of which is developing AI and innovation. We will always back companies to give them a head start in the global race which is why we have recently committed up to £2bn to ensure UK quantum companies can successfully reach commercial scale.
