Hänsel, F. Splatt, M. Harlander, M. Brownnutt, and R. Blatt Today, trapped ion experiments are one of the most advanced prototypes for a quantum computer. However, if the first demonstrations with few ions are to be scaled to a larger number of ions, then different trapping structures will be needed. In Innsbruck, we are investigating two-dimensional as well as three-dimensional miniaturized electrode structures to build traps for scalable quantum computing. In this talk several characterizing experiments and shuttling algorithms in a linear surface trap will be reported. We are able to reliably swap ion positions by using appropriate control voltages on the DC electrodes. In contrast to earlier swapping experiments with a T-shaped trap junction [1], a strictly linear RF potential can be used for the operation. Such a sorting tool may prove useful when different ion species are used for quantum computation. [1] W. K. Hensinger, S. Olmschenk, D. Stick, D. Hucul, M. Yeo, M. Acton, L. Deslauriers, C.
