Oxford Quantum Circuits (OQC)

Enterprise quantum hardware and QCaaS

Overview

Oxford Quantum Circuits (OQC) provides Quantum Computing as-a-Service (QCaaS) built around superconducting qubits and its proprietary Coaxmon architecture. Clients gain access to quantum computing through direct access, managed services, cloud platforms, or colocation data centers, with hardware and software managed by OQC. The Coaxmon qubit design and integration into a scalable QCaaS platform enable users to run quantum workloads without owning and maintaining hardware. OQC differentiates itself through its Oxford university origins, its flagship UK QCaaS platform, and ongoing expansion across Europe and Asia, focusing on enterprise solutions in areas such as climate analytics and artificial intelligence. The company aims to make quantum computing broadly available to businesses by delivering reliable, scalable quantum hardware and service models, supported by ongoing R&D and scalable operations.
