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

Google has accelerated its timeline for achieving cryptographically relevant quantum computing (CRQC)—the theoretical point at which quantum computers could break current encryption standards—to 2029, six years earlier than earlier estimates suggested. This matters because it compresses the window for organizations to transition their systems to quantum-resistant cryptography before such attacks become feasible, forcing enterprises, governments, and infrastructure operators to treat post-quantum migration as an urgent rather than distant priority.
