Does Q-superposition have an effect on bending the spacetime?

My Question;

Does a quantumsuperposition state (wave in Hilbert space) have the ability of influencing the spacetime-continuum?

Thanks

It indeed does. But instead of the classical stress-energy tensor we have a stress-energy operator (in light of quantum formalism).

That's the holy graal of quantum gravity I'd say :-)
What we know (but that's not surprising) is that the space-time continuum has an influence on the wave function. In the other way, something must happen. One way is just to suppose that the "spacetime continuum" (say, the metric tensor) can also be in a "superposition of states".

cheers,

Not an expert in QM. AFAIK, Schrödinger's equation is quite different from the classical wave equation. The former is an equation for the dynamics of the state of a (quantum?) system, the latter is an equation for the dynamics of a (classical) degree of freedom. As a matter of fact, Schrödinger's equation is first order in time derivatives, while the classical wave equation is second order. But, AFAIK, Schrödinger's equation is a wave equation; only its interpretation makes it non-classical...

Is it possible, and fruitful, to use certain conceptual and technical tools from effective field theory (coarse-graining/integrating-out, power-counting, matching, RG) to think about the relationship between the fundamental (quantum) and the emergent (classical), both to account for the quasi-autonomy of the classical level and to quantify residual quantum corrections? By “emergent,” I mean the following: after integrating out fast/irrelevant quantum degrees of freedom (high-energy modes...
