IBM details 520-qubit Nighthawk r3 and a 1,000-qubit link-up plan

IBM said its next Nighthawk r3 quantum processor is planned to run 10,000 quantum operations across 520 qubits and that two r3 processors should be linked into a system exceeding 1,000 qubits in 2027.

IBM reported that customers and partners have already run more than 34 billion circuits on the current Nighthawk r2, with some workloads showing speedups of as much as 19 times over earlier IBM processors.

The company is emphasizing speed as well as scale because useful workloads require millions or billions of circuit samples. The r3 specifications and 2027 link-up remain roadmap targets rather than completed systems.
