The brief

Analyst view
  • Operates Quantum-Compute-as-a-Service via cloud, data center deployment and APIs; systems in Equinix & Digital Realty.
  • Achieved 25-nanosecond two-qubit gates, industry's fastest; targets 50,000+ logical qubits per 300mm wafer.
  • Series C at £260M ($350M) in June 2026, Europe's largest quantum round; led by Bullhound Capital & UK government.

Technical approach

As reported
Gate speed

25-nanosecond two-qubit gates

Industry's fastest benchmark-proven gate times reduce decoherence sensitivity during quantum operations.

Design

Business-ready systems, not prototypes

OQC engineers systems for commercial applications with data center deployment and cloud access support.

Scaling

Roadmap to 50,000+ logical qubits

Targets 1:1 physical-to-logical ratio on 300mm wafers for fault-tolerant systems without massive overhead.
