Chinese Researchers Tap Quantum to Break Encryption

Researchers at Shanghai University leveraged D-Wave’s quantum annealing to factor a 50-bit integer, illustrating a novel optimization-based approach to RSA factorization that, while not threatening current 2048-bit cryptography, signals incremental progress toward practical quantum risks. Experts emphasize that universal, error-corrected quantum capabilities remain years away but advise organizations to inventory current cryptography, enable crypto agility, and plan phased migrations to quantum-resistant standards for long-lived systems.
