Qubit count gets the headlines. Error rates get the analysis. But the classical decoder that must process millions of error signals per second in real time gets almost no attention outside the QEC research community. It may be the capability that determines the CRQC timeline.

Post-quantum cryptography (PQC) is here - not in theory, but in practice. We have concrete algorithms, with standards guiding their implementation. They will replace our decades-old cryptographic infrastructure piece by piece over the next decade. For tech professionals, now is the time to get comfortable with lattices and new key…

Your complete roadmap to quantum-proofing your organization — from boardroom mandate to operational crypto-agility. This practitioner-curated Deep Dive series collects the PostQuantum.com articles you need to launch and run a quantum-readiness program, organized along the lifecycle most teams actually follow: securing executive buy-in and budget, performing cryptographic discovery and inventory,…

This guide is a detailed, end‑to‑end map for understanding what it will actually take to reach a cryptographically relevant quantum computer (CRQC), i.e. break RSA-2048 - not just headline qubit counts. A CRQC must meet two conditions: the algorithmic requirements of the target attack and the hardware capabilities needed to…
