>>> we don't even have a theoretical test to start with Every quantum computing calculation, is a desktop quantum experiment ;) Non-Gaussianity as a signature of a quantum theory of gravity https://arxiv.org/abs/2004.01189 https://arxiv.org/abs/2004.01189 Another cool aspect of the optomechanical tabletop device research was that it wasn't entirely fruitless at all. Although the original mission of finding gravity in quantum space may have failed. The behavior exhibited was so extremely non-classical that an explosion of waveguide manipulating metamaterials was born!
