China breaks quantum code barrier—sparking new concerns over data security

SMRTR summary

Professor Wang Chao of Shanghai University achieved a breakthrough in quantum cryptology by factoring a 90-bit RSA integer using the D-Wave Advantage quantum computer. This combines quantum annealing with classical cryptography and brings us closer to "Q-Day," when quantum computers could break secure encryptions. Experts urge industries to adopt post-quantum cryptography and implement "quantum migration" to protect sensitive data from future quantum decryption.
