Well you only need to find a solution, you don't need to find all solutions (of which there are infinite as you say). Brute force is the only known way currently of discovering a solution, but perhaps Terra Quantum figured out some sort of "shortcut" that reduces the time to find a solution for a particular hash function. Until they release more details I'm highly skeptical you could quickly find a solution to something like sha256
