Testing Quantum Gravity

In view of recent experimental proposals to test gravity in the quantum-mechanical regime, it is crucial to understand which models such experiments can exclude. In this talk, I describe the gravitational interaction between quantum systems as a (possibly noisy) quantum channel, to capture both standard quantum gravity and alternative noisy scenarios. By analyzing the predictions of this general model, I show the optimal strategy to set bounds on or exclude a variety of noisy gravity models in light of current or near-future experiments.
