## Google Aims for Post-Quantum Security by 2029 In a recent announcement, **Google** stated its intention to complete the transition to post-quantum cryptography within the next five years. This proactive approach signals a growing awareness of the potential risks posed by future quantum computers to existing cryptographic systems. While some experts believe that practical quantum computers are still a distant reality, **Google**'s move underscores the value of being prepared. As **Bruce Schneier** notes, "crypto-agility is always a good thing." This transition could incentivize more researchers to scrutinize post-quantum cryptography implementations, potentially uncovering vulnerabilities and strengthening the overall security landscape. The initiative also serves as a signal that even if practical quantum computers are further out than some expect, preparation and vigilance are paramount. Two comments on Schneier's blog post highlight the nuances of this announcement: * **Cley Faye** wonders if this move will lead to more scrutiny and efforts to "break" post-quantum systems. * **Zsolt** suggests that **Google**'s timeline might indicate a degree of uncertainty about the timeline for useful quantum computers.
