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.

      Much less than seconds. The naive algorithm is a loop to 4096 doing one integer divide on each iteration. I think the limiting factor is going to be the memory access to load the code from main memory, so you can say the whole thing can basically be done within the length of time of one memory fetch.

      I still think it’s a significant development. Doing a toy problem on a radically different hardware platform that has the potential to scale up and tackle real-scale problems orders of magnitude more efficiently than the existing architecture is progress. I’m just saying that saying “break RSA” is pure clickbait.
