Google Officially Warns Q-Day Could Arrive as Early as 2029

Google has set its first public timeline for post-quantum migration. VP of Security Engineering Heather Adkins and Senior Cryptology Engineer Sophie Schmieg warn that a cryptographically relevant quantum computer capable of breaking RSA and elliptic curve cryptography could exist as early as 2029. Google is already integrating ML-DSA into Android 17 and has proposed Merkle Tree Certificates to keep post-quantum signature overhead manageable in web PKI.

The world's most widely-used mobile OS and browser are now on a defined PQC schedule. Bitcoin and Ethereum still have no equivalent plan, and the gap is widening by the month.
