IBM Nighthawk r2: Circuit layer operations per second
2,000,000 layers per second
As stated in the source: “2.0M”
Caveats
Live value, rounded, no timestamp; snapshot read 27 Oct 2026. Roughly 6x Heron's 340K; the gain comes mostly from fast reset. IBM's Nighthawk r2 blog quotes throughput as over 100,000 circuits per second (a different measure, not CLOPS). Live value from IBM's calibration table, read on 27 Oct 2026; IBM updates it regularly.
- Set-up
- ibm_phoenix. As listed on IBM Quantum Platform compute resources table; Nighthawk r2 uses fast dissipative qubit reset (idle time between circuits as low as 1 µs).
- Method
- CLOPS (IBM definition; page heading 'CLOPS (or CLOPS_h)')
