Backed by a geographically diverse investor consortium, Universal Quantum says this represents the largest Series A ever raised by a quantum computing company headquartered in the UK. The Brighton-area firm is pursuing a different path than many of its peers: rather than chasing near-term quantum breakthroughs or developing software for existing hardware, it is focused on solving a fundamental challenge—building fault-tolerant quantum computers with millions of error-corrected qubits in an economical, reliable and scalable manner.

Since its founding in 2018, Universal Quantum has now raised more than $125 million in total funding and has secured contracts with the German government. The Series A was co-led by DCVC, the Silicon Valley venture capital firm, and Firgun Ventures, a quantum-focused investor. The round also drew backing from EDBI, the Singapore-based sovereign wealth investor, Integral GlobalTech, a Japanese asset manager, NGS Super, IAG Capital, EdenBase, Eigenstate Holdings, and SiteGround Capital. Dave Baszucki, founder and CEO of Roblox, participated as an individual investor, alongside strategic backers including Nauta Capital and The Venture Collective.

The company intends to deploy the capital toward expanding operations in the United States, Japan and its German hub in Hamburg, while advancing the development and commercialisation of its quantum systems.

Technology and Architecture

Universal Quantum's core innovation centres on the iQPU, or integrated Quantum Processing Unit—a proprietary trapped-ion chip engineered for both manufacturability and performance. The chip is produced on a standard 200mm commercial foundry line, a choice that enables industrial-scale production. With hundreds of ion qubits packed onto a die larger than 400mm², it represents the largest chip of its kind currently in development.

A key differentiator is the chip's reliance on global microwave control rather than traditional laser-based systems. This design choice substantially reduces optical complexity and streamlines the overall architecture compared to competing approaches.

To link multiple iQPUs together, Universal Quantum developed UQConnect, a proprietary interconnect system capable of establishing 2,424 connections per second with ultra-high fidelity of 99.999993%. This modular, tileable design enables organic scaling without the substantial infrastructure overhead or specialised cooling systems required by other quantum platforms. Unlike superconducting quantum systems, Universal Quantum's machines operate at room temperature under standard laboratory conditions, eliminating the need for expensive refrigeration.

Full-Stack Approach

The company has adopted a comprehensive full-stack strategy, developing not only the quantum chips themselves but the entire computing ecosystem surrounding them. This encompasses low-level firmware, quantum circuit optimisation tools, error correction protocols and application-layer software tailored to specific industries including logistics, materials science and pharmaceuticals.

This integrated approach ensures coherence across both hardware and software layers, enabling meaningful collaborations with industrial partners. Rolls-Royce, for instance, is working with Universal Quantum to apply fault-tolerant quantum computing to computational fluid dynamics (CFD), a critical problem in aerospace engineering.

Government Contracts and Global Presence

In 2023, Universal Quantum received a €67 million contract from the German Aerospace Center (DLR)—the largest award ever granted to a UK-based quantum startup. Within the UK, the company has secured multiple Innovate UK-backed projects and participates in national strategy discussions around quantum technology.

The company maintains operations across the United States, Germany, Japan, Denmark and Australia. Notably, Universal Quantum is headquartered in Haywards Heath, Sussex—a commuter town situated between Gatwick Airport and Brighton—rather than in the traditional UK tech hubs of Oxford, Cambridge or Bristol.

Universal Quantum's progress reflects our partners' belief that we represent one of the most credible paths to quantum computing at scale. This round unites an extraordinary group of investors from the world's most important pools of capital around a single mission: delivering utility-scale quantum computing.
