Xanadu and HyperLight Reduce Photonic Switch Loss to 7 mdB

Insider Brief

• Xanadu and HyperLight have demonstrated an optical switch insertion loss of 7 millidecibels (mdB) using HyperLight‘s thin-film lithium niobate (TFLN) Chiplet platform, improving on their previous 20 mdB result from 2025.
• The new result was achieved on a high-volume wafer manufacturing line and is intended to reduce photon signal loss, a key challenge in scaling photonic quantum computers.
• The companies say the improvement could support more efficient manufacturing and the development of larger photonic quantum systems, with potential applications across data centre infrastructure.

PRESS RELEASE — Xanadu Quantum Technologies Limited (“Xanadu”; NASDAQ/TSX: XNDU), a leading photonic quantum computing company, in collaboration with HyperLight Corporation, a leading thin-film lithium niobate (TFLN) photonics company, today announced a significant hardware performance milestone using TFLN technology, reducing optical switch insertion loss to 7 millidecibels (mdB). This achievement represents a nearly threefold improvement over Xanadu and HyperLight’s previous breakthrough of 20 mdB in 2025, drastically reducing qubit signal degradation, which is one of the most critical challenges in scaling quantum computers. This industry-leading achievement was demonstrated using a high-volume wafer manufacturing line on HyperLight’s TFLN Chiplet™ platform and shows excellent yield and repeatability.
