The way you state this illustrates considerable confusion and in these threads I and others have indicated how to think of this. This does not involve gravitons coming out of black holes. You have repeated this error a number of times. A weak low energy quantum gravitation is easy to derive. The low energy limit of gravitation is linear because terms in the curvature involving the square of connection terms are much smaller. This makes gravitation and gravitational waves linear. Quantization is not much different from quantizing electrodynamics in QED. The gravitational waves detected by the LIGO are long wavelength and with small amplitude. There should be signatures of gravitons there which would be linear. As the wavelength shortens the energy increases and as this approaches TeV and higher energy the nonlinear terms become appreciable. The nonlinear feature of gravitation, and that it is an exterior fibration so the field correlates direction with the quantum wave, means this is a nonlinear quantum mechanics, which is a contradiction of quantum mechanics.
