For the weak field limit the nonlinear terms are negligable and a gravitational wave is linear. This is easily quantized. In fact it is similar to the Hanbury-Brown and Twiss theory of the diphoton. It is when the field becomes strong that general relativity becomes nonlinear and runs into trouble with quantum mechanics.
