I haven't read this paper yet, but it does look interesting. For context, there is a famous lecture by Freeman Dyson [1] in which he studies the question of whether it is possible in principle to detect an individual graviton. He considered a couple of different classes of detectors and his conclusions were mostly pessimistic. The essential problem with many detectors (e.g., something like LIGO) is that any detector that is sensitive enough to detect a single graviton would be so massive that it would collapse into a black hole. I'll be curious to see how this new work fits into Dyson's framework.
