Abstract
Techniques for manipulating objects and for determining the position of the objects in parallel dipole line (PDL) trap systems are provided. In one aspect, a PDL trap is provided. The PDL trap includes: a pair of dipole line magnets connected to a potential, wherein the pair of dipole line magnets includes magnets having magnetizations perpendicular to long axes of the magnets; a diamagnetic rod levitating above the pair of dipole line magnets; and at least one electrode above the pair of dipole line magnets, adjacent to the diamagnetic rod. The system produces a hybrid one-dimensional electromagnetic potential which is tunable by voltage. Techniques for operating the PDL trap to manipulate the diamagnetic rod and to detect a position of the diamagnetic rod in the PDL trap are also provided.
