Table-top nanodiamond interferometer enabling quantum gravity tests

Abstract:Along the path of unifying quantum theory and general relativity, it has recently been argued that the observation of gravity-induced entanglement could demonstrate the quantum nature of gravity; a few experimental proposals have been advanced, but extreme technological requirements make their implementation still far. Here we propose a table-top interferometer that, by relying on quantum superpositions of steady nanodiamonds, enables less demanding quantum gravity tests requiring short-range time-varying magnetic fields (much easier to implement) and allowing to recycle the exploited quantum probes (granting shorter acquisition times and increased precision).
