Recent advances push Big Tech closer to the Q-Day danger zone

TL;DR AI
2 min readKey summary
Big Tech, including Google and Cloudflare, is accelerating the shift from RSA and elliptic-curve cryptography to post-quantum algorithms.
New research suggests cryptographically relevant quantum computers may arrive sooner than expected, pushing companies to move faster.
Google and Cloudflare have pulled their internal readiness target up to 2029, while U.S. agencies are setting firm but later migration deadlines.
If powerful quantum computers arrive before upgrades are complete, digital signatures, secure updates, and sensitive communications could be broadly exposed.
