  Single ions held in linear Paul traps are promising candidates for a future
quantum computer. Here, we discuss a two-layer microstructured segmented linear
ion trap. The radial and axial potentials are obtained from numeric field
simulations and the geometry of the trap is optimized. As the trap electrodes
are segmented in the axial direction, the trap allows the transport of ions
between different spatial regions. Starting with realistic numerically obtained
axial potentials, we optimize the transport of an ion such that the motional
degrees of freedom are not excited, even though the transport speed far exceeds
the adiabatic regime. In our optimization we achieve a transport within roughly
two oscillation periods in the axial trap potential compared to typical
adiabatic transports that take of the order 100 oscillations. Furthermore
heating due to quantum mechanical effects is estimated and suppression
strategies are proposed.
