Key takeaways: IBM Quantum Nighthawk r2 uses independent, high-speed qubit reset to execute 100,000+ circuits per second—up to 25x higher circuit throughput than IBM Quantum Heron. Active qubit reset lowers initialization error by around 25x while preserving Heron-class gate fidelity and neighbor-safe operation. IBM Quantum Nighthawk r2 combines 120 programmable qubits, 218 couplers, and 120 reset elements for a total of 458 physical quantum elements. Mid-circuit reset and dynamic circuits make ...
