Quantum error-correction stack enabling fault-tolerant quantum computers MoreLess

Riverlane is a UK-based quantum computing company developing the software infrastructure that will make quantum computers practical and reliable. Founded in 2016 as a spinout from the University of Cambridge, the company is focused on solving one of the biggest technical challenges in the field — quantum error correction. Riverlane’s flagship product, Deltaflow.OS, is a universal operating system designed to control quantum hardware and manage the complex task of detecting and correcting errors in real time. By providing a common software layer across different hardware architectures, Riverlane aims to accelerate the transition from experimental quantum devices to scalable, fault-tolerant quantum computers.

The company collaborates with major industry and research partners worldwide, including leading hardware developers, national laboratories, and government agencies. Through its combination of deep scientific expertise and robust engineering, Riverlane is positioning itself at the core of the emerging quantum computing stack — enabling the next generation of machines to perform reliable computations that classical systems cannot achieve.
