In a nondescript laboratory on the outskirts of Cambridge, engineers stare at screens that flicker with probabilities rather than certainties. On 14 July 2026, Quantinuum, Rolls-Royce, Riverlane and the University of Edinburgh's EPCC formalised a multi-year agreement that moves those flickering probabilities one step closer to solving real problems in industrial design. The focus is narrow at first: modelling the chaotic flow of fluids inside gas turbines. Yet the implications stretch across the delicate balance between private ingenuity and national capability.
The partners will combine Quantinuum's Helios quantum computing platform, with its 98 physical qubits and high two-qubit gate fidelity, alongside Rolls-Royce's deep knowledge of turbine engineering. Riverlane brings its specialised work on quantum error correction, while EPCC contributes supercomputing resources and long experience in knitting classical and quantum systems together. Their immediate task is to test industrially relevant algorithm components on Helios and assess how those pieces might scale to future machines such as Sol and Apollo.
This is not a leap from theory to practice but the next measured stride in work that has already run for nearly five years. Rolls-Royce, Riverlane and EPCC have been refining hybrid fault-tolerant algorithms using classical emulators. The new agreement simply swaps the emulator for actual quantum hardware. Leigh Lapworth, fellow in computational science at Rolls-Royce, captured the shift precisely:
We have been developing and improving algorithms for hybrid fault-tolerant applications for almost five years with Riverlane, using classical emulators in collaboration with EPCC. This agreement marks the start of an exciting new phase where we work together to explore their implementations on Quantinuum's hardware. Applications development is a multi-year activity and if we want to be in a position to benefit from teraQuOp devices, we have to start now, co-developing the algorithms, hardware and software.
The project aligns with the United Kingdom's broader quantum computing mission, which aims to build systems capable of one trillion error-free operations, known as teraQuOp devices. In an era when governments elsewhere pour resources into centralised technology programmes driven by ideological or strategic mandates, this collaboration stands out for its organic character. Established industry, specialist quantum firms and academic supercomputing expertise have come together through targeted, voluntary partnership. No top-down decree set the priorities. The incentive emerged from the genuine computational pain of simulating turbulent fluid dynamics, a task that still taxes even the most powerful classical supercomputers.
Dr Rajeeb Hazra, president and chief executive officer of Quantinuum, described the core difficulty without exaggeration.
The computing demands of simulating complex fluid dynamics are a major challenge in industrial design, and exploring how quantum computing can complement today's supercomputers is an important step toward addressing them. This collaboration will help develop and test the hybrid quantum-classical algorithms needed for future industrial applications.His words underscore a quiet truth: progress here depends less on grand promises than on patient integration of new tools into existing industrial workflows.
Steve Brierley, chief executive officer and founder of Riverlane, emphasised the foundational role of error correction.
