The quantum computer, called Starling, will use 200 logical qubits — and IBM plans to follow this up with a 2,000-logical-qubit machine in 2033

IBM says it’s overcoming a quantum computing challenge with new error-correction techniques for fault-tolerant systems.

IBM Corp. today revealed its expected roadmap for building the world’s first large-scale, fault-tolerant quantum computer, which would enable scaling up quantum computing for real-world practical results.
