How is curvature of spacetime defined in quantum mechanics or qft?

It isn't.

QM deals with the very small in the form of particles. GR deals with the very large in the form of fields.

I imagine it be like two parallel string which is fields n jumping from one string to another cost energy n all the atom is connected to space n space is made of many many fields.energy taken by fields may be compared with the redshift. Can u write a formula for this mr james?
