Description
Laser cooled atomic ions offer unprecedented control over both internal and external degrees of freedom at the single-particle level. They are considered among the foremost candidates for realizing quantum simulation and computation platforms that can outperform classical computers in specific tasks. Trapped ions can be used to simulate effective models of lattice gauge theories and to simulate their real-time dynamics. I will briefly cover recent advances in the use of trapped ions for digital quantum simulation of the Schwinger model [1,2]. I will then report on recent proposals and ongoing experimental efforts to simulate real-time dynamics of the Schwinger model in an analog fashion with either tailored two-body interactions [3] or higher-order spin-spin interactions [4]. Finally, I will discuss a hybrid digital-analog approach [5] to simulate the Yukawa and Schwinger models by a more efficient mapping of these theories onto the degrees of freedom of the trapped-ion simulator.
