Chinese researchers break RSA encryption with a quantum computer


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.
