The paper has an abstract but no conclusion section. Is it a preprint? Has it been through peer review?
I’m also skeptical because it says one of the two masses involved has to be in quantum superposition. I guess it’s a neat party trick if we can use it to levitate a couple atoms, but we can do that better with EM charges or maybe even spin. I don’t think this will enable antigravity hoverboards even if we could put an entire board into two quantum states at once.
The experiment they propose to test the theory involve two masses about the size of a cell. So, big enough that it might someday (in the next 10 years they think) be possible to detect the gravitational waves, but small enough that they can still be entangled. If gravity is truly quantum in nature, the gravitational waves will be too, which is what they want to look for.
