Colour Centres in Silicon
A Modality Made for Scale
Optically-Linked Silicon Colour Centre Qubits
T centres—a unique type of colour centre—underpin Photonic’s unique architecture and were specifically chosen to deliver the distributed entanglement essential to high performance, commercial-scale quantum computing and quantum networking.
A T centre is a stable, scalable, high-performance atomic structure with up to four spin qubits and an inherent optical interconnect, allowing integrated memory, computation, and communications in a single structure. This unique structure is the key to overcoming the barriers to manufacturing, controlling, connecting, and correcting high volumes of qubits.
Thousands of T centres can be housed in each modular Quantum Processing Unit (QPU) and can communicate locally and remotely—efficiently leveraging the infrastructure and scale of silicon.
A New Paradigm to
Scale Up and Scale Out
From the beginning, Photonic has taken a systems engineering approach—considering cost, efficiency, and ease of implementation as systems are scaled up. T centres maintain high performance at just 1K, reducing cooling equipment and power overhead for lower costs compared to other quantum architectures. Likewise, Photonic’s system architecture prioritizes distributed entanglement using the T centre’s built-in silicon photonic interconnect, enabling any-to-any connectivity between remote qubits. This facilitates efficient entanglement distribution over telecom fibre and brings fault tolerance within reach with highly efficient, low-overhead QLDPC codes.
