IBM unveils Condor (1,121 qubits), Heron and Quantum System Two

IBM/Starling fault-tolerant roadmap

IBM debuted Heron, a 133-qubit processor with 5x error reduction over Eagle, and Quantum System Two, its first modular quantum computer. Heron is available via cloud access; System Two operates with three Herons at Yorktown Heights. IBM also extended its roadmap through 2033, shifting focus from raw qubit counts to gate quality and utility-scale applications.

• Heron: 133-qubit processor with 5x error reduction over Eagle; engineered over four years.
• Quantum System Two: modular architecture with three Heron processors; foundation for future generations.
• Roadmap extended through 2033 emphasizing operational quality and integration with classical computing.
• Focus shifted from qubit count to gate quality and practical utility-scale chemistry, physics, materials science apps.
