Chinese mathematicians break military standard encryption using quantum computer. 中國數學家利用量子電腦破解了軍用標準加密.
RSA is an industry standard (public key) cryptography protocol. At 2048 bit length, it’s estimated that someone trying to crack an encrypted message using a powerful digital computer would need millions (10’s-100’s of million) of years to crack it. Thus the entire architecture of the internet (secure data storage, private messaging, secure payments, private accounts, secure websites (the “s” of https), secure passwords, privacy in general) is built on the reliability of such encryption.
A Chinese research team has demonstrated that this encryption can be cracked using readily available quantum computers.

The research team, led by Wang Chao from Shanghai University, found that D-Wave’s quantum computers can optimize problem-solving in a way that makes it possible to attack encryption methods such as RSA.
In a potentially alarming development for global cybersecurity, Chinese researchers have unveiled a method using D-Wave’s quantum annealing systems to crack classic encryption, potentially accelerating the timeline for when quantum computers could pose a real threat to widely used cryptographic systems.
Published in the Chinese Journal of Computers under the title “Quantum Annealing Public Key Cryptographic Attack Algorithm Based on D-Wave Advantage,” the paper outlined how D-Wave’s machines were used to break RSA encryption and attack symmetric encryption systems, raising serious questions about the future of cybersecurity.
