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.

Does this attack scale linearly with key size?
Using the D-Wave Advantage, we successfully factored a 22-bit RSA integer, demonstrating the potential for quantum machines to tackle cryptographic problems
That attack is a threat only if it scale better than existing attacks.
