A new era of quantum computing may pose threats closer than we think, Google warns

Google warned that advances in quantum computing could undermine today’s encryption and digital signatures sooner than expected.

The company says it plans to move its own systems to post-quantum cryptography by 2029.

If current encryption breaks, banking, communications, and critical infrastructure could face major exposure.

Governments and companies are being urged to migrate early to quantum-resistant security before the threat becomes practical.
