Quantum computers are powerful but error-prone. IBM says it’s overcoming this challenge with new error-correction techniques for fault-tolerant systems.

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 unveiled plans for the world’s first large-scale, fault-tolerant quantum computer, with scalable quantum computing.
