Google: The quantum apocalypse is coming sooner than we thought - csoonline.com

Google warns that large-scale quantum computers could break widely used encryption standards like RSA and ECC by 2029, accelerating the timeline for a potential "quantum apocalypse" that threatens global cybersecurity infrastructure. The tech giant has set a 2029 deadline for organizations to adopt quantum-resistant cryptographic algorithms, urging immediate preparation to mitigate risks to financial systems, government communications, and critical infrastructure. Current encryption methods—relied upon by banks, militaries, and cloud services—will become vulnerable once error-corrected quantum machines achieve sufficient scale, potentially enabling adversaries to decrypt sensitive historical and real-time data. Google’s announcement aligns with growing industry consensus that post-quantum cryptography (PQC) migration must begin now, as upgrading systems could take a decade or more due to complexity and legacy dependencies. The warning underscores a shift from theoretical risk to imminent threat, with experts emphasizing that proactive measures—such as NIST-approved PQC standards—are critical to prevent catastrophic breaches before quantum capabilities mature.
