IBM sets 2029 target for quantum breakthrough
The Starling system will be IBM’s first practical quantum computer, marking a key milestone in reducing qubit errors through a new design-first approach.
IBM has set out a detailed roadmap to deliver a practical quantum computer by 2029, marking a major milestone in its long-term strategy.
The company plans to build its ‘Starling’ quantum system at a new data centre in Poughkeepsie, New York, targeting around 200 logical qubits—enough to begin outperforming classical computers in specific tasks instead of lagging due to error correction limitations.
Quantum computers rely on qubits to perform complex calculations, but high error rates have held back their potential. IBM shifted its approach in 2019, designing error-correction algorithms based on real, manufacturable chips instead of theoretical models.
The change, as the company says, will significantly reduce the qubits needed to fix errors.
With confidence in its new method, IBM will build a series of quantum systems until 2027, each advancing toward a larger, more capable machine.
Vice President Jay Gambetta stated the key scientific questions have already been resolved, meaning what remains is primarily an engineering challenge instead of a scientific one.
