Two of us (CM and VV) recently showed how the quantum character of a physicalsystem, in particular the gravitational field, can in principle be witnessedwithout directly measuring observables of that system, solely by its ability tomediate entanglement between two other systems. Here we propose a variant ofthat scheme, where the entanglement is again generated via gravitationalinteraction, but now between two particles both at sharp locations (very closeto each other) but each in a superposition of two different masses. We discussan in-principle example using two hypothetical massive, neutral,weakly-interacting particles generated in a superposition of different masses.The key property of such particles would be that, like neutrinos, they areaffected only by weak nuclear interactions and gravity.

Quantum-gravity effects could in principle be witnessed in neutrino-like oscillations
