Universal Quantum, a University of Sussex spinout founded in 2018, has raised US$100 million in Series A funding, making it the largest Series A round raised by a UK-headquartered quantum computing firm. The Haywards Heath-based company is focused on building fault-tolerant quantum computers with millions of error-corrected qubits for real-world use. The capital will accelerate its expansion in the United States, Japan, and its German hub in Hamburg while supporting the development and commercialization of its modular quantum technology.
Investor Base and Capital Strategy
The Series A round was co-led by Silicon Valley venture firm DCVC and Firgun Ventures, a quantum-focused investor. Other participants included EDBI, Integral GlobalTech, NGS Super, IAG Capital, EdenBase, Eigenstate Holdings, SiteGround Capital, and Roblox founder and CEO Dave Baszucki. Existing backers Nauta Capital and The Venture Collective also joined the round, reflecting support from geographically and strategically diverse pools of capital.
Scalable Trapped-Ion Architecture
Universal Quantum is building its integrated Quantum Processing Unit, or iQPU, as a proprietary trapped-ion chip fabricated on a standard 200 millimeter commercial foundry line. Each chip hosts hundreds of ion qubits on a die larger than 400 square millimeters and uses global microwave control instead of traditional laser systems. The company has also developed UQConnect, an interconnect that links chips at a rate of 2,424 connections per second with an ultra-high fidelity of 99.999993%.
Contracts, Partners, and Regional Growth
The company has secured a partnership with Rolls-Royce to apply fault-tolerant quantum computing to computational fluid dynamics, a core challenge in aerospace engineering. In 2023, Universal Quantum received a EUR 67 million contract from the German Aerospace Center, the largest ever granted to a UK-based quantum startup. The investment also supports a regional ambition to establish a Quantum Silicon Valley in the Sussex and Brighton area, attracting talent, investment, and innovative businesses.
Leadership Perspective
Dr. Sebastian Weidt, CEO and co-founder of Universal Quantum, said the company's progress reflects partners' belief that it represents one of the most credible paths to quantum computing at scale. He added that the 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. Weidt co-founded the company with Professor Winfried Hensinger from the Sussex Centre for Quantum Technologies.
Market Context and Full-Stack Approach
The funding arrives as the quantum technology market is projected to reach up to US$100 billion by 2035, driven by potential applications in drug discovery, advanced materials, and energy systems. Universal Quantum has adopted a full-stack strategy, designing chips, low-level firmware, circuit optimization tools, error correction protocols, and application-layer software. This end-to-end integration aims to support partnerships in logistics, materials science, and pharmaceuticals.
The company has now raised more than US$125 million in total and operates in the United States, Germany, Japan, Denmark, and Australia. This latest funding strengthens the University of Sussex's track record of translating fundamental research into commercial success and supports the wider Sussex and Brighton quantum ecosystem. By advancing modular, room-temperature quantum computing, Universal Quantum is positioning itself as a credible player in the race to deliver utility-scale machines.
