IBM Unveils Nighthawk r3 Quantum Processor, Plans 1,000+ Qubit System by 2027
IBM announced its next-gen Nighthawk r3 processor supports 520 qubits and 10,000 operations, with plans to link two units into a >1,000-qubit system in 2027.
US tech giant IBM (NYSE: IBM) announced on November 11, 2026, that its next-generation quantum processor, IBM Quantum Nighthawk r3, is designed to accurately execute 10,000 quantum operations across 520 programmable qubits. The company also disclosed a roadmap to connect two Nighthawk r3 processors into a single system with more than 1,000 qubits in 2027.
The announcement builds on the performance of the current generation, Nighthawk r2. Introduced in September, r2 supports accurate computations with over 7,500 quantum operations on 120 qubits and delivers up to 100,000 samples per second. IBM reported that clients and partners including E.ON, Algorithmiq, and Q-CTRL have executed more than 34 billion circuits on r2, achieving speedups of up to 19x compared to previous IBM quantum processors.
Specific use cases include energy company E.ON reporting a 15x speedup in quantum machine learning for grid optimization, and an experiment with Oak Ridge National Laboratory simulating magnetic materials achieving a 12x speedup. These results were benchmarked against earlier work on the IBM Quantum Heron processor. Additionally, IBM and RIKEN scientists used the new hybrid platform to execute sample-based quantum diagonalization workflows roughly 5 times faster while performing 100 times more computations.
To enable modular scaling, Nighthawk r3 introduces 10 chip-to-chip interconnects called l-couplers. IBM stated that it has already demonstrated connecting two Nighthawk r1 processors using four l-couplers, achieving 99.3 percent quantum state transfer fidelity, and successfully connected two cryogenic modules into a single system for the first time. These advances aim to address engineering bottlenecks in large-scale quantum computing and push the industry toward fault tolerance.
