Description
Formulating bosonic field theories for quantum simulation is a subtle task. Ideally, one wants the smallest truncation of the bosonic Hilbert space that simultaneously exhibits a high degree of universality. But many of the most straight-forward truncations probably do not exhibit much universality. Meanwhile, recent work on the so-called "fuzzy" sigma model has shown promise as a very efficient qubitization of the 1+1d sigma model, with only a 4-dimensional 1-site Hilbert space. In this talk we discuss the generalization of the fuzzy strategy to non-abelian gauge theories. We argue that a promising gauge theory can be constructed based on the Orland-Rohrlich gauge magnet, and we contrast this "fuzzy" gauge theory with the traditional Laplacian truncation strategy.
