Does Q-superposition have an effect on gravity?

    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?

    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".
