Register-based ion traps are among the leading approaches for scalable quantum processors. These are defined by the spatial division of different operations such as storage, state preparation and readout. A fundamental characteristic of the register-based approach is the translation of ions to reach the different registers of the QCCD architecture. Here, we discuss registers interconnected through a x-junction. We will focus on the necessary through-junction transport.
We will present the different constraints applied to our optimization algorithm in order to obtain trapping potentials for different ion species. Besides, we will also discuss additional conditions that allow a reliable trough-junction transport.
