You Don’t Need Quantum Hardware for PQC Readiness Now

🔐 Cloudflare explains that post-quantum cryptography (PQC) protects communications against future quantum computers and does not require specialized quantum hardware. PQC runs today on existing phones, servers, and network infrastructure, can scale at Internet level, and in many cases matches or exceeds classical performance. The post argues that quantum technologies like QKD and QRNG are interesting scientific tools but are neither necessary nor sufficient for broad post-quantum security; organizations should prioritize cryptographic agility and migration to PQC.
