Oxford Quantum Circuits

Oxford Quantum Circuits (OQC) is an Oxford-based quantum computing company that develops superconducting quantum processors using a proprietary qubit architecture called Coaxmon, which stores quantum information in a 3D structure rather than a flat 2D chip, enabling better qubit isolation and higher fidelity. OQC provides cloud access to its quantum processors through its Toshiba-backed cloud service and through AWS Braket, making it accessible to enterprise and research customers globally without on-premises quantum hardware. The company was the first commercial quantum computer provider in the UK and has established a European quantum computing cloud to serve enterprise and government customers requiring data residency within the EU. OQC focuses on hardware improvements that demonstrate a clear path to fault-tolerant quantum computing rather than maximizing near-term qubit count. Founded in 2017 as a spinout from Oxford University, OQC has raised over $100M from investors including Toshiba and SoftBank, and positions itself as the European alternative to IBM and Google in the quantum computing cloud market.
