A promising approach for a trapped-ion based quantum computer is the quantum-charge-coupled-device architecture, as it enables scalability by use of micro-fabrication methods. While using a junction naturally allows all-to-all connectivity of the qubit-array, it is more time efficient to resort to swapping operations for a certain fraction of qubit-shuffles. We present a trap design based on a linear Paul trap that is capable of driving near-field gradient two-qubit gates as well as swapping, merging and splitting two-ion crystals. It also features storage registers using the bucket brigade approach. We will show simulation results that allow extraction of ions from the storage registers as well as merging and swapping.
