Qudit stabiliser codes for $\mathbb{Z}_N$ lattice gauge theories with matter
Abstract
In this work we extend the connection between Quantum Error Correction (QEC) and Lattice Gauge Theories (LGTs) by showing that a gauge theory with prime dimension coupled to dynamical matter can be expressed as a qudit stabilizer code. Using the stabilizer formalism we show how to formulate an exact mapping of the encoded gauge theory onto two different bosonic models, uncovering a logical duality generated by error correction itself. From this perspective, quantum error correction provides a unifying language to expose dual descriptions of lattice gauge theories. In addition, we generalize earlier constructions on qubits to on -level qudits and demonstrate how universal fault-tolerant gates can be implemented via state injection between compatible qudit codes.
