A motion step to move n atoms is shown. n atoms are sequentially targeted by the addressing beams and transferred from the ‘stationary’ state to the ‘motion’ state using microwaves. The electro-optic modulator (EO) voltages are ramped up to the half-wave voltage (Vλ/2) in order to move atoms by half of the lattice spacing. After motion, the atoms are optically pumped so that they all return to the stationary state. The EO voltages are then ramped back down. A final optical pumping (OP) ensures optimal preparation for the next motion step.
