Briefings

Xanadu and HyperLight achieved a 7 millidecibel (mdB) optical switch insertion loss using their TFLN Chiplet platform, a nearly threefold improvement over the 20 mdB result from 2025. This milestone was demonstrated on a high-volume wafer manufacturing line, addressing a critical challenge in scaling photonic quantum computers by reducing photon signal loss and preserving quantum state fidelity.

Key points

• Xanadu and HyperLight achieved a 7 millidecibel (mdB) optical switch insertion loss using their TFLN Chiplet platform, a nearly threefold improvement over the 20 mdB result from 2025.
• The achievement was demonstrated on a high-volume wafer manufacturing line, addressing a critical challenge in scaling photonic quantum computers by reducing photon signal loss and preserving quantum state fidelity.

Context

Xanadu Quantum Technologies Limited and HyperLight Corporation announced this hardware performance milestone using TFLN technology. The partnership supports the development of larger photonic quantum systems and utility-scale quantum computing, with potential applications across data center infrastructure.

Limitations

The evidence is limited to a single press release from November 2026. It does not include independent verification, long-term stability data, or comparative analysis against other competing technologies. The reported yield and repeatability are based on the specific manufacturing line demonstration.
