QM doesn’t assume space is discrete. It does deal with a number of discrete quantities though. Are you sure that’s where the conflict is? I think people have done QM with a given curved spacetime, just, where the spacetime manifold isn’t decided based on the distribution of matter and whatnot? Like, I think that’s where the ideas of Hawking radiation come from?
