Post-Quantum Crypto Readiness Accelerates — Q-Day Potentially 2029, Only 40% of Top Websites Support Hybrid PQC

Ars Technica·medium signal

Ars Technica reports that recent advances in quantum computing are pushing Big Tech closer to 'Q-Day' — potentially as early as 2029 based on Google's estimates. Research suggests Shor's algorithm could work with 10,000-20,000 atomic qubits. Google Chrome and Cloudflare already support PQC in some protocols, Android 17 will integrate ML-DSA, but only 38% of organizations globally are transitioning. Gartner elevated PQC migration to board-level priority in late 2025. For builders: if you're not evaluating PQC for your TLS stack, the window is closing.
