Oxford Quantum Circuits (OQC) is a UK quantum-computing scaleup developing superconducting quantum systems. The company has raised $158M total: $40.5M Series A (2022) + $100M Series B (Nov 2023). Lansdowne Partners + British Patient Capital are among the lead backers (Source: OQC Newsroom; eeNews Europe).
OQC's proprietary Coaxmon 3D qubit architecture places qubit components on opposite sides of the substrate to simplify wiring and improve coherence — a variant of the transmon. The OQC Cloud offers a 32-qubit enterprise platform for compute-as-a-service (Source: eeNews Europe; DCD).
OQC published a 2025-2034 technical roadmap targeting ~200 logical qubits by 2028 and 50,000 logical qubits by 2034. In 2025 OQC integrated a real-time QEC decoder via Riverlane partnership — first of its kind in the UK (Source: OQC + Riverlane Press Release; eeNews Europe).
