Shor, QLDPC Codes, and the Compression of RSA-2048 Resource Estimates (Part I)

Does institutional risk modeling account for non-linear improvements in error-correction efficiency, or has the timeline for a cryptographically relevant quantum computer (CRQC) narrowed beyond existing forecasts? The technical baseline for evaluating RSA-2048 was updated in February 2026 with the “Pinnacle Architecture” analysis (arXiv:2602.11457). This research identifies a specific pathway to reduce the physical qubit overhead […]
