Google bumps up Q Day deadline to 2029, far sooner than previously thought

2026-03-26

Q Day is the point at which existing quantum computers can break public-key cryptography algorithms. Everyone should prepare by adopting post-quantum cryptography (PQC) algorithms. Google is now giving itself until 2029 to prepare for the event. The beta version of Android 17 will add support for developers to have PQC keys for signing their apps and verifying other software signatures.
