*Executive summary:* Google is developing and testing Merkle Tree Certificates (MTCs) for Chrome to enable post-quantum secure TLS without large certificate chains, working with Cloudflare and Certificate Transparency operators. The company plans a three-phase rollout — feasibility testing (in progress), CT log bootstrapping (Q1 2027), and full onboarding into a Chrome Quantum-resistant Root Store (CQRS) by Q3 2027 — aiming to maintain performance while improving post-quantum authentication.
