ORCA Computing, founded in 2019 as a University of Oxford spin-out and headquartered in London with offices in Canada and the US, develops full-stack photonic quantum computing systems. Their modular, fibre-interconnected architecture enables scalable, upgradable quantum photonic systems designed for near-term applications in generative AI, machine learning, and optimization, while maintaining a roadmap toward fault-tolerant universal quantum computing. ORCA's PT Series quantum photonic systems are rack-mounted, data centre-ready, and developer-friendly, integrating with industry-standard tools like PyTorch and CUDA-Q. The company has delivered 10 on-premises quantum photonic systems globally by early 2025, serving clients including the UK Ministry of Defence, National Quantum Computing Centre, Poznan Supercomputing and Networking Center, and Montana State University. ORCA's technology offers superior scalability, lower barriers to entry, and a commercial path to fault tolerance, positioning it as a leader in practical quantum computing solutions for scientific and industrial applications.
