• Abstract summary: We provide entanglement-based protocols to test the magnetically induced dipole-dipole interaction and the Casimir-Polder potential between the two nano-crystals. We show that it is possible to close the SG interferometer in position and momentum with a modest gradient in the magnetic field.

• Abstract: Quantum entanglement provides a novel way to test short-distance quantum physics in a non-relativistic regime. We provide entanglement-based protocols to potentially test the magnetically induced dipole-dipole interaction and the Casimir-Polder potential between the two nano-crystals kept in a Schrodinger Cat state. Our scheme is based on the Stern-Gerlach (SG) apparatus, where we can witness the entanglement mediated by these interactions for the nano-crystal mass m~10^-19 kg with a spatial superposition size of order 0.1 micron in a trap relying on diamagnetic levitation. We show that it is possible to close the SG interferometer in position and momentum with a modest gradient in the magnetic field.

  We investigate the role of rotation in a matter-wave interferometer, where we show that imparting angular momentum along the direction of a defect can cause an enhancement in spin contrast. The imparted angular momentum can enhance the spatial superposition by almost a factor of two and possibly average out any potential permanent dipoles in the nanodiamond.
