In March 2026, Riverlane published a Quantum Error Correction roadmap targeting one million error-free quantum operations (MegaQuOp) by end-2026 — a milestone the company says can accelerate utility-scale quantum computing by 3-5 years (Source: Riverlane Press Release; HPCwire).
Riverlane's 2025 integration of a real-time QEC decoder into OQC's system was the first of its kind in the UK. The QEC research field has exploded — 120 new peer-reviewed papers in the first 10 months of 2025 (vs 36 in all of 2024) (Source: OQC + Riverlane Press Release; Riverlane QEC Report 2025).
