Next-generation trapped-ion quantum computing system

ORAL

Abstract

The first generation of a trapped ion-based integrated quantum processor, constructed in a collaboration between universities and industrial partners, was used to perform quantum algorithms with high-fidelity on 12 qubits, and high-fidelity quantum gates with up to 23 qubits. We are now building a second-generation system with an improved design benefiting from the building and operating the current system. The new system has a capacity of 32 qubits and parallel addressing capability using an RF-on-a-chip system. This work presents the recent progress in constructing the system with the upgraded optical design and the new-generation micro-fabricated surface ion trap from Sandia National Laboratories.
