Abstract
Precise control of the transport of ultracold 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. Remarkably, this device achieves high sensitivity to small changes in magnetic-field orientation, using a nonentangled initial state, making it a promising candidate for sensing applications.
