- Abstract: Despite the fact that we have some proposals for the quantum theory of
gravity like string theory or loop quantum gravity, we do not have any
experimental evidence supporting any of these theories. Actually, we do not
have experimental evidence pointing in the direction that we really need a
quantum description of the gravitational field. In this scenario, several
proposals for experimentally investigating quantum gravitational effects far
from Plank scale have recently appear in literature, like gravitationally
induced entanglement, for instance. An important issue of theses approaches is
the decoherence introduced by the quantum nature not only of the system under
consideration, but also from the gravitational field itself. Here, by means of
the Feynman-Vernon influence functional we study the decoherence of a quantum
system induced by the quantized gravitational field and by its own quantum
nature. Our results may be important in providing a better understanding of
many phenomena like the decoherence induced by the gravitational time-dilation,
the quantum reference frames and the quantum equivalence principle.

Proposed experiments with superposed gravitational sources would provide even stronger evidence that gravity is nonclassical.

It is concluded that, within the framework of Quantum Mechanics, there is absolutely no reason to believe in the existence of non-Local effects.
