So far, to my knowledge, not faster than a classical system. We've been searching for decades for a problem with a better quantum solution than a classical solution, and it's been a tough slog. These are, at least thus far and from my limited perspective, very special-purpose accelerators. Shor's algorithm is the one thing that comes to mind tbh. "Breaking crypto" in this case isn't anything other than finding prime factors of an integer.
