Advancing Towards Quantum Advantage
summary
IBM outlines a concrete roadmap: public quantum data centers in New York and Germany, demonstrated 127-qubit experiments with ~2,880 two‑qubit gates in 2023 using error mitigation, and targets to demonstrate quantum advantage by 2026. Hardware moves from the Heron processor (133–156 qubits, tunable couplers, median two‑qubit error ~1.5×10⁻³) to Nighthawk (120 qubits, square-lattice connectivity) to enable thousands‑to‑tens‑of‑thousands gate circuits and modular fault tolerance by 2029.
