Laser-free control of trapped ion qudits.

POSTER

Abstract

Demonstration of quantum advantage remains challenging due to the increased overhead of controlling large quantum systems. While significant effort has been devoted to qubit-based devices, qudits (d-level systems) offer potential advantages in both hardware efficiency and algorithmic performance. We present laser-free, multi-tone control of a trapped ion qudit up to dimension eight, as well as progress towards qudit entangling gates.
