IBM details a modular path to the Starling fault-tolerant quantum computer
IBM published an updated roadmap and two preprints for a modular qLDPC-based architecture, targeting Starling in 2029 with 200 logical qubits and 100 million quantum gates. It specified intermediate chips, inter-module links, magic-state operations, and a real-time decoder.
Why it matters: The roadmap translated 'fault tolerant' into architectural components and measurable milestones, making the claim more falsifiable than a generic qubit-count promise.
