MAKING QUANTUM COMPUTING
A PRACTICAL REALITY

We develop full-stack photonic quantum computers to unlock new fields of applications, accelerate innovation and help transform industries. Our vision is to create both near-term, value-creating quantum accelerators and long-term, error-corrected quantum computers. We do this through a single technology: ORCA’s modular, fibre-interconnected architecture.

By combining novel technology with rack-mounted telecom and optical fibre components, ORCA provides a unique approach to deliver the performance, scalability and usability to begin addressing use-cases such as generative machine learning and optimisation.

ORCA PT Series

An Approach to Quantum Computing Like No Other

Our mission is to develop near-term industrial applications of quantum accelerated generative AI and optimisation. ORCA PT Series quantum photonic systems are built on the demonstrated success of real-world applications and deployments in the field. Quite simply, they function, operate, and perform like no other quantum computer and are a welcome departure from the cumbersome, fragile, and costly systems in the industry.

QUANTUM ACCELERATED GENERATIVE AI AND OPTIMISATION

Generative AI is impacting every industry and organisation. The combination with quantum computing will profoundly advance organisations while disrupting the unsustainable demand for power consumption. ORCA’s PT Series delivers capabilities not found in any other classical and quantum computing platform.

The ORCA PT Series has already been applied to a wide range of applications and use-cases in generative AI and optimisation. Results have been achieved with researchers and enterprises in several scientifically and industrially important use-cases.
