One of the outstanding requirements for realising quantum computing with trapped ions is the implementation of a truly scalable trap architecture. Proposals for such architectures include segmented linear Paul traps, where the segmentation allows the axial confining potential to be varied. Ions can thereby be independently held in - and moved between - separate trapping regions. We present numerical models of linear shuttling of ions in such traps, and of optimised shuttling through junctions. We also report on developments in fabrication and testing of various segmented trap designs. Finally, work regarding practical aspects of vacuum chamber design will be outlined.
