OQC outlines bold 50,000 qubit quantum computing vision

The firm says it can reduce error rates and scale fault-tolerant systems efficiently.

Quantum applications in finance and cybersecurity are closer than many realise, says OQC.

Oxford Quantum Circuits (OQC) has revealed plans to develop a 50,000 qubit fault-tolerant quantum computer by 2034, using its proprietary ‘Dimon’ superconducting transmon technology.

Achieving such scale would require millions of physical qubits but promises to outperform global rivals, including Google and IBM, with real-world applications ranging from cyber threat detection to drug discovery.

The roadmap includes a significant push to reduce error rates and optimise chip materials, with recent breakthroughs enabling error detection at the hardware level. OQC claims it achieves a 99.8% gate fidelity in just 25 nanoseconds and a tenfold improvement in qubit efficiency compared to competitors.

Interim CEO Gerald Mullally said the roadmap marks a turning point, calling on finance and national security organisations to prepare for a quantum-driven future.

Now seeking $100 million in Series B funding, the firm plans to install its first quantum system in New York, later this year.
