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.

If its true it is a big “achivement”, but it still did not broke RSA.
Speak for yourself. I’m going to migrate all of my 22-bit RSA keys to a longer key length. And not 24 bits, either, given that they’re probably working on a bigger quantum computer already. I gotta go so long that no computer can ever crack it.
64-bit RSA will surely be secure for the foreseeable future, cost be damned.
honestly while I agree that slightly longer keys wont be safe for long , but tbh I’m gonna sit a bit more on my 23-bit RSA keys before migrating
It means that if quantum technology improves, the same technique can break higher bit integers. So it’s in fact broken, we just don’t have the future hardware to execute it on yet.
