IBM has revealed its roadmap for bringing a large-scale, fault-tolerant quantum computer, IBM Quantum Starling, online by 2029, which is significantly earlier than many technologists thought possible.

The company says it has cracked the code for error correction and is building a modular machine in New York state.

The world’s largest industrial research organization has revealed its plans to develop the first large-scale, fault-tolerant quantum computer, paving the way for practical and scalable quantum computing by the decade’s end.
