Abstract

Multilayer surface-electrode ion traps provide a scalable platform for quantum processors. In this paper we present a demonstrator chip designed to implement an 8-qubit shuttling-based quantum processor with chip-integrated microwave control for quantum gates. The design is based on a linear Paul trap geometry. All-to-all connectivity will be implemented through ion swapping. The production of the trap chip is carried out with multistep microfabrication. The 2-layer ion trap chip with two storage registers and an interaction zone has a size of 5mm x 10mm. Flexibility in signal routing is improved through the use of thick and planarised metal–dielectric layers.
