Xanadu and HyperLight Reduce Photonic Switch Loss to 7 mdB

AI-summarised brief · reviewed before publication

Xanadu Quantum Technologies and HyperLight Corporation announced a breakthrough in photonic quantum hardware, reducing optical switch insertion loss to 7 millidecibels (mdB) on HyperLight’s thin‑film lithium niobate (TFLN) Chiplet platform. The achievement, nearly three times better than the 20‑mdB benchmark set in 2025, was demonstrated on a high‑volume wafer line, indicating strong yield and repeatability. Lower loss preserves quantum state fidelity, enabling larger, more efficient photonic quantum systems and potentially benefiting data‑center infrastructure.

💡 Why It Matters

  • · Ultra‑low switch loss directly addresses the most critical bottleneck in scaling photonic quantum computers, moving the technology closer to fault‑tolerant, commercially viable systems.
