Certainly not within our lifetimes, within our species lifetimes, who knows. We need to be able to probe the planck energy scale to observe quantum gravity effects. That is around 10^16 TeV, to put that into perspective, the LHC collision energy is 14 TeV. Below the planck scale, gravity is too weak to be measured at the quantum level.
