Beschreibung
Trapped atomic ions serve as powerful digital, analog, and hybrid quantum simulators for many-body quantum systems using their spin and motional degrees of freedom. Our experiment is based on a chain of 171Yb+ ions with individual laser beam addressing, creating a fully connected device capable of executing any sequence of single- and two-qubit gates, as well as continuous evolution involving the motional degree of freedom. We recently simulated the real-time dynamics of a lattice gauge theory in 1+1 dimensions, i.e., the lattice Schwinger model, and reported the comparison of different error mitigation strategies for this application [1]. Mapping the bosonic degrees of freedom to qubits makes such simulations challenging. The motional modes of trapped ions are a bosonic quantum resource that can be used directly for efficient implementations. We describe first results from an analog-digital hybrid quantum simulation of the Yukawa model, proposed in [2], that employs motional modes along multiple directions.
