- Abstract: The quantum simulation of dynamical gauge field theories offers the
opportunity to study complex high-energy physics with controllable low-energy
devices. For quantum computation, bosonic codes promise robust error correction
that exploits multi-particle redundancy in bosons. In this Letter, we
demonstrate how bosonic codes can be used to simulate dynamical gauge fields.
We encode both matter and dynamical gauge fields in a network of resonators
that are coupled via three-wave-mixing. The mapping to a $\mathbb{Z}_2$
dynamical lattice gauge theory is established when the gauge resonators operate
as Schr\"odinger cat states. We explore the optimal conditions under which the
system preserves the required gauge symmetries. Our findings promote realising
high-energy models using bosonic codes.
