Photonic Inc., headquartered in Vancouver, is developing a quantum computing architecture that uses color centers in silicon to create spin-photon interfaces. This approach combines the proven manufacturability of silicon semiconductor processes with photonic networking, potentially enabling distributed quantum computing over fiber optic connections. The company is one of four selected for Canada's Phase 1 quantum initiative.
The approach matters because it leverages existing silicon fabrication infrastructure, which could dramatically reduce the cost and complexity of scaling quantum computers compared to exotic materials approaches. Photonic interconnects also enable modular architectures where quantum processors can be networked, addressing one of the fundamental scalability challenges in quantum computing.
Photonic represents a distinctly Canadian bet: using the country's strength in both photonics research (centered around Waterloo and Vancouver) and silicon device physics to pursue a differentiated path to practical quantum computing. The company's inclusion in the federal quantum program alongside Xanadu, Nord Quantique, and Anyon Systems reflects the government's portfolio approach to a technology where the winning architecture remains uncertain.
