First find a graviton. No one has yet.

That would be something difficult to do because of the weakness of gravity wit respect to the other interactions. Unless, of course, there are large extra dimensions like what has been proposed in some string theory models, in which case they could be detected in the Large Hadron Collider.
There are two problems with quantum gravitation:
1. No one has yet detected a graviton
2. All of the quantum gravitation theories have renormalization problems.
Which is why string theory is such an attractive thing. It can reproduce a quantum theory of gravitation without the infinities. It does not need to be renormalized. BUT there are 10^500 possible string theories and no empirical way to find the one that its the facts. String theory predicts too much and is, in a practical sense, untestable.
