Title:
Impact of Rotations on Stern-Gerlach Interferometry utilizing Nitrogen Vacancy defect Nano Diamonds

Abstract:
The singular Nitrogen-Vacancy (NV) defect Nano Diamond (ND) is a well demonstrated tool for mesoscopic quantum entanglement research. The spin-magnetic field interaction properties of such ND are utilized in Stern-Gerlach Interferometer (SGI) setups, where the use of massive object spatial quantum superposition allows for testing quantum theory in new regimes, more specifically probing quantum gravity. While this setup is promising, rotational degrees of freedom of the ND may lead to loss of information, warranting further analysis of the impact of rotations on the SGI scheme. We model the impact of rotations on the spatial and angular trajectory of SGI paths and draw conclusions on optimal settings for minimizing incorrect spin measurement.
