## Summary

UK-based quantum computing company providing cloud access to superconducting processors using proprietary Coaxmon 3D qubit architecture; first commercial quantum computer provider in UK; available via AWS Braket and Toshiba-backed European quantum cloud.

## Company Overview

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.

## Frequently Asked Questions

### What is OQC's Coaxmon qubit design?
Coaxmon is OQC's proprietary superconducting qubit architecture that uses a 3D coaxial structure to isolate qubits from their environment, reducing interference from nearby qubits and the substrate, achieving higher gate fidelity than traditional 2D chip designs.

### What is Oxford Quantum Circuits?
Oxford Quantum Circuits (OQC) is a UK-based quantum computing company that builds superconducting quantum processors using its proprietary Coaxmon architecture and offers cloud-based quantum computing access for research and enterprise customers.

### How much has OQC raised?
OQC raised $100 million in a Series A in 2022 — at the time the largest quantum computing funding round in Europe — from investors including NTT and SBI Investment, reflecting strong Japanese strategic interest in quantum technology.

### What cloud platforms provide OQC access?
OQC provides quantum computing access through Amazon Braket and direct API access, making its Coaxmon-based quantum processors available to cloud customers worldwide alongside systems from IonQ, Rigetti, and others.

### Where does OQC operate quantum systems?
OQC operates quantum computing systems in the UK and has expanded with a quantum computing facility in Japan following its partnership with NTT and SBI, extending its geographic reach beyond Europe.

### What is OQC's commercial focus?
OQC targets pharmaceutical, financial services, and aerospace industries for near-term quantum computing applications, as well as government and defense research programs through partnerships with national research institutions.

### Is OQC publicly traded?
No, Oxford Quantum Circuits is a privately held quantum computing company headquartered in Reading, UK, spun out from the University of Oxford.

### Who founded Oxford Quantum Circuits?
OQC was founded in 2017 by Dr. Ilana Wisby (CEO) and Professor Peter Leek (now CTO) from Oxford University, commercializing the Coaxmon qubit architecture developed in Leek's academic research lab.
