English abstract One of the greatest challenges of science is to understand the current accelerated expansion of the Universe. In this work, we show that by considering the quantum nature of the gravitational field, its wavelength can be associated with an effective Compton mass. We propose that this mass can be interpreted as dark energy, with a Compton wavelength given by the size of the observable Universe, implying that the dark energy varies depending on this size. If we do so, we find that: 1.- Even without any free constant for dark energy, the evolution of the Hubble parameter is exactly the same as for the LCDM model, so this model has the same predictions as LCDM. 2.- The density rate of the dark energy is ΩΛ =0.69 which is a very similar value as the one found by the Planck satellite ΩΛ =0.684. 3.- The dark energy has this value because it corresponds to the actual size of the radius of the Universe, thus the coincidence problem has a very natural explanation. 4.It, is possible to find also a natural explanation to why observations inferred from the local distance ladder find the value H0 =73 km/s/Mpc for the Hubble constant. We show that if we take the variability of the dark energy into account, they should measure H0 =67.3 km/s/Mpc as well. 5.- In this model the in ationary period contains a natural successful graceful exit
