IBM: ‘Verified Quantum Advantage’ By 2026, ‘Fault-Tolerant Quantum Computing By 2029

Quantum computing continues to heat up, and IBM is at the front of it.

In my post today at Forbes …

IBM announced major progress toward practical quantum computing at its Quantum Developer Conference in New York, forecasting verified quantum advantage by 2026 and fault-tolerant quantum computing by 2029. The company unveiled the 120-qubit Quantum Nighthawk processor, the experimental Quantum Loon for fault tolerance, and breakthroughs including a 10× speedup in error correction and a 100× reduction in the cost of error mitigation.

IBM has also shifted to 300-mm wafers and increased chip complexity tenfold, accelerating its development cycle. Alongside its hardware milestones, IBM launched a new open Quantum Advantage Tracker with partners like Algorithmiq and the Flatiron Institute to independently verify progress across the industry. The initiative reflects a growing push for transparency as over 80 global quantum companies race toward demonstrable, peer-reviewed quantum advantage.
