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.
As a matter of opsec, I mostly agree. But security is always best achieved in layers (and to a degree, redundancy). People running any CIA/NSA-backdoored operating system are compromised before even thinking about being discrete.
Always assume you will be surveilled. Always assume you will be caught. Ultimately it’s strong encryption and total rejection of closed-source software that gives you the best defense against the pigs.
But at what cost?

The best defence is always going to be being unknown.
