On the Development of a Fully Integrated Shuttling Controller System on Chip for Trapped-Ion Quantum Computing
Alexander Meyer, Вадим Іссаков · 2025
This paper presents an overview of the latest research results on integrated, cryogenic-compatible electronics for ion shuttling operation in Trapped-Ion Quantum Computers (TIQCs). Integrated circuit (IC) realization is essential to enable system scaling towards a larger number of qubits. Firstly, we review the specific challenges related to the shuttling operation and ion confinement. Consequently, implications on circuit design of an integrated shuttling controller system on chip (SoC) are discussed. Particularly, among other circuit design parameters, we analyze in detail the requirements on power and area consumption, noise performance, and cryogenic-compatibility. Secondly, we provide an overview on reported discrete solutions, eventually highlighting the need for a dedicated integrated shuttling controller SoC. Hence, state of the art integrated shuttling controller approaches are presented and reviewed. Finally, we conclude the paper with an outlook on promising integrated circuit concepts for shuttling controllers.
