IBM’s Nighthawk & Loon Chips Set Pace for 2026 Quantum Advantage—and a Fault‑Tolerant Era by 2029 (Nov 16, 2025)
Sunday, November 16, 2025 — Daily update on IBM’s new quantum roadmap milestones, industry reaction, and what’s next. Key facts at a glance What IBM announced—and why it matters IBM used its Quantum Developer Conference to unveil two chips that split the roadmap into near‑term utility and long‑term fault tolerance: IBM is also publishing progress beyond hardware: Qiskit v2.x performance improvements (including faster transpilation) and a new Quantum Advantage Tracker—an open, community‑led site with contributors from IBM, Flatiron Institute, Algorithmiq, and BlueQubit—for documenting claims and the classical baselines they must beat.
