Using LIGO to prove the existence of gravitons

In 2013, Dr. Freeman Dyson published a paper which details the concept of single graviton detection. In this paper he examines various types of graviton detection and explains why they are impossible. One of the methods he examined was that of using LIGO to detect gravitons. The section where he discusses detecting gravitons with LIGO is what I will be making a poster of for the APS meeting
