Google warns quantum era could threaten current security systems

Google says a new era of quantum computing could challenge the foundations of online security sooner than many expect, Euronews writes.

Cybersecurity experts have sounded the alarm for years about quantum computers becoming so powerful that they could break the public encryption systems that protect our online conversations, bank accounts, and most vital infrastructure, wreaking havoc on governments and businesses.

In a blog post, Google said that “quantum computers will pose a significant threat to current cryptographic standards, and specifically to encryption and digital signatures”.

Google said it is setting a timeline to migrate to post-quantum cryptography (PQC) by 2029, urging other companies to follow suit. The company warns that action is needed before “a future quantum computer can break current encryption.”
