128 bytes isn't going to contain a very large database. (More generally,
quantum computers won't help with problems - and there are a lot of them -
that are more constrained by RAM than CPU speed.)

Computational chemistry is something quantum computers would be useful for.
But kiloqubit-range machines are only going to be able to simulate systems
with a handful of atoms.
