IBM Quantum Nighthawk r3: 520-qubit processor for 10,000 quantum operations

IBM has announced the IBM Quantum Nighthawk r3, its next-generation quantum processor built to accurately execute 10,000 quantum operations across 520 programmable qubits. The announcement on November 11, 2026, advances the company's quantum computing scale and speed.

What happened?

The Nighthawk r3 retains the high-speed architecture of the previous r2, which reached up to 100,000 samples per second. With 520 programmable qubits and 2,034 total physical qubits, the new chip enables more complex circuits. In 2027, IBM plans to link two r3 processors into a single system with more than 1,000 qubits.

Why does this matter?

Useful quantum computing depends on both quality and speed. The r3 increases the number of accurately executable operations, helping larger problems in areas such as drug discovery and optimization. The modular strategy using l-couplers allows scaling beyond a single chip.

What changes in practice?

Users of the IBM Quantum Platform will be able to explore more demanding circuits. The company has already seen over 34 billion circuits run on the r2 by partners including E.ON and Algorithmiq, with speedups of up to 19x. The r3 accelerates the path to fault tolerance, targeted for 2029 with the Starling system.
