IBM Releases Nighthawk r2 QPU Featuring Active Dissipative Qubit Reset and 25x Circuit Throughput - Quantum Computing Report

IBM Quantum has announced the official release of IBM Quantum Nighthawk r2 (deployed as ibm_phoenix), its fastest quantum processing unit (QPU) to date. Built on a square-lattice architecture, the 120-qubit processor introduces a high-speed dissipative qubit reset framework that eliminates long inter-circuit idle periods, achieving a maximum circuit throughput of over 100,000 circuits per second—a 25x speedup over IBM’s Heron QPU fleet (~4,000 circuits per second).
