They work, but it’s expensive and POC stage. They’re mostly just not scaled to the level that we think we can take them to.
Comment on Regarding this picture, where do you think quantum computers lie and why?

Pretty sure QC is down at 0,0 right now. They haven’t gotten it to work in the way it’s been envisioned yet. The theory is there, but until something is quantifiably working, there’s basically no hype behind it.

I’d say very slightly past that. Quantum computers do work right now, but it’s the same way the Wright brothers’ first plane worked: as proof of concept and research, but not better than existing tech for solving any problems.
And it’s not that they fail to meet expectations of the designers, as far as I know they do exactly what they are built to do as well as predicted with the tech we have. Just the press is expecting more.

The users of quantum computing is also such that if it does work, the 3 letter agencies will want to keep it to themselves and decrypt as much as possible before admitting it even exists.

Unfortunately for them, most of the progress is coming from the private sector (like most cutting edge tech these days) and those guys like to brag too much to let NSA come in and say “hey can we use that on the dl for about 3 years before you say anything”

Isn’t post-quantum cryptography already a thing? Probably not implemented in anything meaningful yet, but still.

Signal has it yes

There are plenty of dual-use technologies. That is, one’s that have both a private sector and military application. The big secret agencies rarely keep these things to themselves. The economic advantages of QC are too great to just sit on.
