What happened
This document bundles three Google Security Blog posts (Feb 2026) with product and standards announcements: 1) Chrome announced a program to adopt quantum-resistant HTTPS via Merkle Tree Certificates (MTCs) developed in the IETF PLANTS working group. Chrome will not immediately add traditional post‑quantum X.509 roots to the Chrome Root Store; instead it is piloting MTCs (Phase 1 underway in collaboration with Cloudflare), with Phase 2 bootstrapping public MTCs in Q1 2027 using experienced CT log operators, and Phase 3 (Q3 2027) to finalize onboarding requirements and create a Chrome Quantum‑r
