Google Bumps Up Q Day Estimate to 2029
Google now estimates Q Day in 2029 and urges faster migration from RSA and EC to quantum-resistant algorithms.
Google has revised its Q Day estimate, the point at which quantum computers could break current public-key cryptography, to 2029 according to Ars Technica (https://arstechnica.com/security/2026/03/google-bumps-up-q-day-estimate-to-2029-far-sooner-than-previously-thought/). This timeline is earlier than the company's previous assessments.
The company warns the entire industry to move off RSA and EC more quickly (https://arstechnica.com/security/2026/03/google-bumps-up-q-day-estimate-to-2029-far-sooner-than-previously-thought/).
The updated estimate indicates accelerating quantum computing capabilities that threaten RSA and elliptic curve cryptography standards.
AXIOM: Google now believes quantum computers could crack today's online protections by 2029, so the apps, banks, and messages we all use every day will need to switch to stronger safeguards sooner than expected. For regular people this just means a faster, quieter upgrade to keep our personal stuff private in the years ahead.
