Qudit stabilizer codes for ZN lattice gauge theories with matter
Luca Spagnoli, Alessandro Roggero, and Nathan Wiebe
arXiv:2602.20661 [quant-ph] ()In this work we extend the connection between Quantum Error Correction (QEC) and Lattice Gauge Theories (LGTs) by showing that a \(ZN\) gauge theory with prime dimension \(N\) coupled to dynamical matter can be expressed as a qudit stabilizer code. …

Improving Quantum Multi-Objective Optimization with Archiving and Substitution
Linus Ekstrom, Takafumi Hosogi, Xavier Bonet-Monroig, Sebastian Schmitt, Hao Wang, and Thomas Bäck
Presented at The 11th International Conference on Machine Learning, Optimization, and Data Science (LOD) 2025 ()Finding optimal solutions of conflicting objectives is a daily matter in many industrial applications, with multi-objective optimization trying to find the best solutions to them. The advent of quantum computing has led to researchers wondering if …

Fault-tolerant simulation of Lattice Gauge Theories with gauge covariant codes
Luca Spagnoli, Alessandro Roggero, and Nathan Wiebe
Quantum 10, 1968 () | arXiv:2405.19293 [quant-ph]We show in this paper that a strong and easy connection exists between quantum error correction and Lattice Gauge Theories (LGT) by using the Gauge symmetry to construct an efficient error-correcting code for Abelian \(Z2\) LGTs. We identify the …
