IBM announced the Nighthawk r3 quantum processor and enhancements to the IBM Quantum Platform in a press release issued on November 11, 2026, disclosing processor specifications, partner performance results, and plans to link two r3 processors into a 1,040-qubit system in 2027.

Key Highlights

  • Nighthawk r3 specifications: The new processor is designed to support 10,000 quantum operations on 520 programmable qubits, with 2,034 total physical qubits.
  • Planned 1,040-qubit system: IBM disclosed plans to connect two Nighthawk r3 processors into a single system in 2027.
  • Partner circuit volume: Clients and partners including E.ON, Algorithmiq, and Q-CTRL have executed 34 billion circuits on Nighthawk r2, reporting performance improvements of up to 19x over previous IBM quantum processors.
  • Chip-to-chip interconnects: Nighthawk r3 introduces 10 l-couplers designed to connect processors into larger systems; IBM reported 99.3 percent quantum state transfer fidelity in a prior test using four l-couplers on Nighthawk r1 processors.
  • Classical-quantum integration: IBM and RIKEN scientists executed a sample-based quantum diagonalization workflow roughly 5 times faster while performing 100 times more computations using the enhanced IBM Quantum Platform.
  • Cryogenic module milestone: IBM reported connecting two cryogenic modules into a single system for the first time, reaching operating temperature in under five days and cooling below 15 millikelvin.

IBM Nighthawk r3 Processor Details and Platform Advances

According to the announcement, IBM Quantum Nighthawk r3 is designed to accurately execute 10,000 quantum operations across 520 programmable qubits and 2,034 total physical qubits. The processor retains the square-lattice connectivity and fast operations of its predecessor while adding 10 chip-to-chip interconnects, called l-couplers, intended to link processors into larger systems. IBM (NYSE:IBM) disclosed that in 2027 it plans to join two Nighthawk r3 processors into a single 1,040-qubit system.

The filing describes the currently available Nighthawk r2, introduced in September, as capable of delivering up to 100,000 samples per second while supporting accurate computations with more than 7,500 quantum operations on 120 qubits. E.ON reported a 15x speedup on Nighthawk r2 for quantum machine learning applied to energy grid optimization, according to the release. IBM separately reported a 12x speedup in an experiment run with Oak Ridge National Laboratory simulating magnetic materials, with results described as consistent with neutron scattering experiments. Both speedups were achieved over previous work on IBM Quantum Heron, the filing states.

On the platform side, the announcement describes IBM Quantum Platform as now bringing high-performance classical and quantum computing together into a single managed environment. Cleveland Clinic and RIKEN are cited as having used the platform to automatically process 608 million samples for modeling biologically relevant structures, described as 33 times faster than without workflow automation. The release also notes that IBM launched a co-design platform for quantum error correction with Oak Ridge National Laboratory and AMD, physically co-locating Nighthawk with ORNL's Umbra High-Performance Computing system, powered by AMD Instinct MI355X GPUs and 5th Gen AMD EPYC CPUs.
