Abstract

Precise control of the transport of ultra-cold atoms in optical lattices is essential for the exploration of quantum phenomena and the development of advanced quantum technologies. Harnessing the distinctive characteristics of the system near integrability, we investigate the tunneling control of dipolar bosons confined within a triple-well circuit via dipole polarization orientation. Based on this control mechanism, we propose a quantum magnetic compass that shows sensitivity beyond the Heisenberg limit to small variations in the orientation of magnetic fields, making it a promising candidate for sensing applications.
