Quantinuum Demonstrates Helix Quantum Error Correction Architecture on Helios Hardware

Quantinuum experimentally validated its Helix quantum error correction architecture on its 98-qubit Helios processor, achieving world-record logical memory error rates and significant improvements in logical gate fidelities without relying on postselection. This demonstration includes a complete fault-tolerant stack and outlines scalability through concatenated code variants for future hardware generations.
