IBM Quantum Nighthawk r2—more circuits, faster
Summary
IBM's Quantum Nighthawk r2 introduces independent, high-speed qubit reset via a dissipative reset gadget, enabling over 100,000 circuits per second—roughly 25x faster than Heron. It uses 120 programmable qubits, 218 couplers, and 120 reset elements to deliver high-throughput, low initialization error, and supports dynamic circuits and quantum error correction research. The system demonstrates 7,500+ gate circuits with maintained gate fidelity and is available on the IBM Quantum Platform with a 2026 roadmap milestone.
