Xanadu and HyperLight say they reduced optical switch insertion loss to 7 millidecibels, compared with their 20 millidecibel result in 2025. The companies announced the result on November 10 and said they demonstrated it using a high-volume wafer manufacturing line on HyperLight's thin-film lithium niobate platform.

The switches route photons carrying quantum information. Reducing the light lost during switching helps preserve those signals, which cannot be conventionally amplified without destroying their quantum states. Xanadu cautioned that the testing milestone may not deliver the expected system-level efficiencies, fault tolerance or manufacturing cost reductions.
