OQC ^Company

OQC provides quantum computing solutions and services for enterprises and research institutions.

OQC (Oxford Quantum Circuits Limited) is a UK-based quantum computing company (founded 2017 as a spin-out from the University of Oxford, headquartered in Reading, UK) specializing in superconducting quantum computers using a unique 3D coaxial architecture for scalable, high-fidelity qubits. It develops full-stack systems (e.g., OQC Toshiko enterprise-ready platform, OQC Titan roadmap for commercial advantage) offered as Quantum Computing as a Service (QCaaS) via cloud access. Focus areas include biotech (quantum simulations for molecular modeling and drug discovery), cybersecurity (quantum-accelerated optimization for post-quantum crypto analysis), and communications (quantum network simulation, secure quantum links). OQC partners with Equinix Metal (data centers), NTT Docomo, and European initiatives. Total funding raised: ~$158–$200M+ across rounds (largest: ongoing Series B $100M+ led by SBI Investment in Nov 2023, with Chevron joining later; prior Series A £38M in Jul 2022).
