IBM Nighthawk r2 Tops 100,000 Circuits per Second with New Reset Architecture
IBM has made its Nighthawk r2 processor available on the IBM Quantum Platform. The 120-qubit device introduces a qubit-reset architecture that IBM reports delivers up to 25 times the circuit throughput of its Heron systems, exceeding 100,000 circuits per second.

This throughput increase could make practical quantum error mitigation techniques that require large numbers of circuit executions, improving the quality of results on Nighthawk r2 for chemistry and optimization workloads within the next two years.
Methods like zero-noise extrapolation and probabilistic error cancellation multiply the number of circuits that must be run, and previous throughput made them expensive on cloud processors. A 25-fold increase reduces sampling time from hours to minutes, assuming gate error rates on Nighthawk r2 are comparable to Heron and users adopt existing Qiskit Runtime error mitigation tools.
