Riverlane

Riverlane is a pioneering quantum computing software company focused on developing quantum error correction and operating system technologies essential for fault-tolerant quantum computing. Founded in 2016 by Steve Brierley, the company has built Deltaflow, a comprehensive quantum software platform that provides the classical infrastructure needed to control and manage quantum computers at scale. Riverlane’s technology addresses one of quantum computing’s most critical challenges: managing the complex classical computation required for quantum error correction in real-time. The company’s approach involves building specialized hardware and software systems that can process the massive amounts of syndrome data generated by quantum error correction codes. Riverlane has established partnerships with major quantum hardware companies and research institutions, working to standardize quantum error correction protocols and develop the software infrastructure for million-qubit quantum computers. As the quantum industry moves toward fault-tolerant systems, Riverlane’s expertise in quantum error correction positions them as a crucial enabler of practical quantum computing applications.

2025 Developments: In September 2025, Riverlane’s Deltaflow 2 platform installed at Oak Ridge National Laboratory, first dedicated real-time QEC integration at U.S. national lab. Raised £15 million Series B from Molten Ventures, Altair, Cambridge Innovation Capital, Amadeus Capital Partners, and National Security Strategic Investment Fund. Awarded £2.1 million Horizon Europe grant for quantum error correction decoder development. In March 2024, Rolls-Royce, Riverlane, and Xanadu secured £400,000 for quantum jet engine modelling
