Ions held in micro-structured segmented electrodynamic traps (microtrap) are promising candidates for a future quantum computer. A large number of DC electrodes are required for shuttling and separation of trapped ions as well as for controlling the range and magnitude of coupling between ions.

We have developed a versatile electric field generator (EFG) [1] to provide arbitrary DC potentials up to 24 DC electrodes of the microtrap experimental setup [2]. The microtrap has mainly two (loading and processing) regions. In both regions we have performed trapping, shuttling, splitting and recombination of Yb+ ion strings. We will present recent results on the manipulation of ion strings.
