Google Cloud Sets Quantum-Ready Timeline with 2029 Deadline

Google Cloud has set out its roadmap for migrating to post-quantum cryptography (PQC), aiming to reach full readiness by 2029. The tech giant accelerated its timeline due to faster-than-expected advances in quantum hardware and error correction.

The plan focuses on three priority areas: mitigating Store Now Decrypt Later risk, strengthening digital signatures against forgery, and building cryptographic agility for adopting new standards as they emerge.

Some milestones have already been achieved. Google Cloud's API endpoints now use NIST-standardized ML-KEM key exchange in hybrid mode, while application and proxy load balancers support quantum-safe hybrid key exchange for TLS 1.3 on an opt-in basis.

The company is also working on hardware-backed protections, including confidential computing and Cloud HSM, which are slated for 2028. Google notes that it will continue efforts into the 2030s to support broader industry guidance and evolving global standards.
