Toronto-based Xanadu and Boston’s HyperLight have achieved a major milestone in quantum hardware, announcing record-low waveguide and switch losses in thin-film lithium niobate (TFLN) chips. With waveguide losses under 2 dB/m and switch loss of just 20 mdB, the chips meet critical performance thresholds for scalable, commercial photonic quantum computing.
Fabricated in high-volume semiconductor facilities, the chips align with Xanadu’s roadmap for utility-scale quantum systems. The breakthrough builds on their recent Aurora networked quantum computer demo. Both firms credit their longstanding collaboration as key to the result.
