What Is a Cryptographically Relevant Quantum Computer (CRQC)? A Practitioner's Reference for CISOs and Security Architects

Every post-quantum cryptography conversation eventually circles back to the same foundational question: what, precisely, is the threat model? Vendor briefings invoke quantum computing loosely. Board members conflate quantum communication with quantum computation. And well-intentioned security teams sometimes dismiss the risk entirely because today's quantum hardware cannot factor a
