Personally I find quantum computers really impressive, and they havent been given its righteous hype.
I know they won't be something everyone has in their house but it will greatly improve some services.

The uses/advantages 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.
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.
Isn't post-quantum cryptography already a thing? Probably not implemented in anything meaningful yet, but still.
Signal has it yes
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"
