Google is sounding the alarm on quantum computers

Google has issued a warning about the potential threat that quantum computers pose to current encryption methods. The blog post highlights that quantum systems can evaluate many possibilities simultaneously, allowing them to tackle problems that would take classical computers an impractical amount of time. This includes breaking public key encryption schemes that secure online banking, private messages, corporate data, and government communications. Google emphasizes the urgency of transitioning to post-quantum cryptography, as attackers could potentially decrypt stored encrypted data once quantum computers reach the necessary scale. The company also points out the challenges of updating legacy systems and the importance of widespread adoption of common standards to avoid a fragmented security landscape.
