1) Be nice and; have fun
Doxxing, trolling, sealioning, racism, and toxicity are not welcomed in AskLemmy. Remember what your mother said: if you can't say something nice, don't say anything at all. In addition, the site-wide Lemmy.world terms of service also apply here. Please familiarize yourself with them
2) All posts must end with a '?'
This is sort of like Jeopardy. Please phrase all post titles in the form of a proper question ending with ?
3) No spam
Please do not flood the community with nonsense. Actual suspected spammers will be banned on site. No astroturfing.
4) NSFW is okay, within reason
Just remember to tag posts with either a content warning or a [NSFW] tag. Overtly sexual posts are not allowed, please direct them to either [email protected] or [email protected].
NSFW comments should be restricted to posts tagged [NSFW].
5) This is not a support community.
It is not a place for 'how do I?', type questions.

Reminder: The terms of service apply here too.

Sure, researching these algorithms is a valid concern. Just advertising is misleading. Since there are no quantum computers around which would be big and reliable enough to do these calculations. And as far as I know we're not even sure if we can buld them at all, or in what timeframe. So they're advertising to protect against something that doesn't exist. I think that should be factored in when comparing services.
And by the way: I think it's mainly the key exchange that is affected. I guess the tunnels are protected with symmetric cryptography? And quantum isn't really an issue for most symmetric cryptography algorithms.
Exactly.
And yes, the handshake is made over an assymetric cipher, and then you use a symmetric one because they (this is not true for all symmetric algorithms out there, but the ones used in ssh etc. are) are both way faster and actually safe against quantum algorithms.
