Post-Quantum Crypto Race Intensifies as Big Tech Players Diverge on Readiness

Ars Technica·medium signal

Ars Technica reports that recent advances in quantum computing are pushing Big Tech closer to the 'Q-Day' danger zone — the point when quantum computers can break current encryption. Some companies (Google, Cloudflare, Apple) are accelerating post-quantum cryptography migration while others lag behind. The divergence in readiness across the industry means some critical infrastructure may remain vulnerable when quantum threats materialize.
