Photonic Chips Cut Loss to 2 dB/m with Xanadu, HyperLight

A collaborative effort between Xanadu and HyperLight has yielded advancements in thin-film lithium niobate (TFLN) photonic chips, demonstrating waveguide losses below 2 dB/m and a switch loss of approximately 20 milli-decibel (mdB). These results, achieved in a high-volume semiconductor production facility, represent a performance benchmark for electro-optic switches intended for photonic quantum computing applications and build upon Xanadu’s recent demonstration of Aurora, a fibre-networked photonic quantum computer leveraging HyperLight’s TFLN Chiplet platform. The achievement highlights the potential of TFLN technology, synergized with datacom and telecom applications, to enable high-performance quantum computing hardware.
