IBM sets 2026 target for quantum advantage, fault-tolerant quantum computing by 2029

IBM announced during the 2025 Quantum Developer Conference on Wednesday that it expects to reach quantum advantage by 2026, while targeting full-scale fault-tolerant quantum computing by 2029. The company confirmed that its Nighthawk processor, a chip with major architectural upgrades, will start reaching users this year. Jay Gambetta, who leads IBM Research as Director and also holds the title of IBM Fellow, said, “We believe that IBM is the only company that is positioned to rapidly invent and scale quantum software, hardware, fabrication, and error correction to unlock transformative applications.” Jay added that the company is announcing several critical milestones on its roadmap today. Nighthawk, now revealed as IBM’s most advanced chip yet, is built with 120 qubits and uses 218 tunable couplers to link each qubit to its four nearest neighbors. That’s a 20% increase in coupler count compared to the Heron processor, according to an official press release...
