Only Asymetric encryption, like PGP has Problems with Quantum Computers. Symmetric, like AES, used by dm-crypt is not affected by Quantum Computers. It doesn’t rely on multiplied big prime numbers or stuff like that.
The question isnt whether quantum computers have an advantage over regular computers (they pretty much always do for code cracking as the parallel superposition computation is some crazy shit that changes cryptography forever) instead the question is whether or not AES-256 is able to resist our current quantum compute and how long it can do that.
Its a simple equation, as long as it takes longer than the lifespan of the universe to compute with our most powerful supercomputers its considered good encryption. However as computers get more powerful, the projected time decreases potentially to the point of human lifespan time frames. Thats when it becomes a problem and the standard fails.
Currently AES is quantum resistant but it almost certainly won’t be forever. New standards are gonna need to be adopted at some point.

Is it a proved theorem that quantum computers dont have an advantage for AES, or is it just unkown?
