At QDC 2026 IBM announced the IBM Quantum Nighthawk r3 processor, slated for 2027, with 520 programmable qubits (2,034 physical) capable of 10,000 accurate two-qubit operations and a planned 1,040-qubit system via two-chip links. The roadmap shows Nighthawk r2, deployed in September 2026, already ran over 34 billion circuits for partners such as E.ON, Algorithmiq and Q-CTRL, delivering speedups up to 19× versus Heron. Benchmarks with Algorithmiq highlighted an 8× faster square-lattice execution but required roughly 240× more classical memory for tensor-network approximations. IBM demonstrated four chip-to-chip l-couplers with 99.3% state-transfer fidelity and a dual-module cryogenic system cooled below 15 mK in under five days. New software includes Managed Workflows in the IBM Quantum Functions stack, a Rust-based QRMI for HPC schedulers, and pulse-level dynamic circuit tools supporting million-round repetition codes. 1
