Abstract
A method is presented, which includes trapping a charged particle at a first position using an electromagnetic trap and providing a static magnetic field at the first position such that a qubit transition of the charged particle is defined, and providing, using an entangling electrode, an oscillating magnetic field. The oscillating magnetic field present at the first position does not contain a polarisation component which directly couples to the qubit transition. The oscillating magnetic field has a spatial gradient at the first position, of the polarisation component of the oscillating magnetic field which couples the qubit transition to the motion of the charged particle.
