NISQ.OS (Deltaflow.OS quantum operating system)
A Riverlane-led consortium that built Deltaflow.OS, an operating system meant to run the same software on different kinds of quantum hardware.
Project data last updated 11 October 2026
About this project
The consortium was awarded a £7.6 million grant in May 2020. It brought together UK quantum hardware companies working on silicon, photonic, superconducting and trapped-ion qubits, plus Arm and the National Physical Laboratory.
The project set out to give users access to each layer of the quantum computing stack so that tasks can be scheduled well. NPL's role was to help define a standard interface between software and hardware.
