Error correction and fault tolerance

Logical qubits; codes (surface, qLDPC, concatenated, bosonic); below threshold and break even results; decoders and real time decoding; magic states; fault tolerance architectures and roadmaps (IBM Starling, Quantinuum Apollo, Milestone 3); QEC benchmarks.

Not here: Error mitigation and suppression (Software, algorithms and advantage); generic hardware specifications (Quantum computing hardware).
