That's how it's been explained to me by laymen many many times. Just casually (ish, I have a math degree) looking at the math, chatting with a friend who is a quantum physicist, being involved with computers, etc I find that Grover's Algorithm is not at all capable of something like that. I'm not sure there's anything better in terms of breaking encryption

https://en.wikipedia.org/wiki/Grover%27s_algorithm

Grover's algorithm could brute-force a 128-bit symmetric cryptographic key in roughly 264 iterations, or a 256-bit key in roughly 2128 iterations. It may not be the case that Grover's algorithm poses a significantly increased risk to encryption over existing classical algorithms, however.[4]

I am stoked for what it could do for protein folding, or other heavy simulation work, but in terms of proper encryption I don't believe it actually will change much.

current encryption algorithms

The encryption-scares don't really bother me. It's as if everyone thinks quantum computers will come of age but for some reason quantum encryption won't equally scale up to match it?

Like, of course current encryption methods are at risk, they aren't designed to match quantum computing and any that would, while it would be nice if it also performed on current PC's... it wouldn't need to in the longrun.

I do agree that the in-between time of "Oh shit, a quantum computer was invented" and "Ta-da! Encryption that chokes QC!" is a bit scary. Here's hoping most devs take measures and precautions during the first few warning-shot hours lol.
