Surface-electrode ion traps are a promising platform for scalable quantum computers. In the Quantum CCD architecture, transport of ions between registers allows to limit the number of ions that has to be kept in a single potential well at any given time and to implement specialized registers for storage, cooling, detection and gate operations. Here we present the design of a demonstrator chip based on an X junction and quantum gate operations with chip-integrated microwave conductors. This design has been developed with the goal of increasing the storage capacity, optimizing laser access and improving gate operations.
