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.
I mean this one could actually be at a big cost. It would take a lot of effort to switch the world’s digital systems to be fully quantum secure, but this situation was inevitable either way.
There’s never going to be a such thing as quantum secure. Cryptography is an arms race. All we can really do is make the maths more complicated and take longer; all attackers can do is try to reduce the time it takes.
But at what cost?
