  "authors": [
    "Rowan Brad Quni-Gudzinas"
  ],
  "abstract": "This note documents a due-diligence assessment of the trapped-ion qudit quantum computing program led by Martin Ringbauer at the University of Innsbruck. Three publications anchor the assessment: the universal qudit processor demonstration (2022), the native qudit entanglement gate based on a generalized light-shift mechanism (2023), and a lattice gauge theory simulation with ion qudits (2024). All bibliographic metadata, author lists, DOIs, and experimental figures cited here were verified against live Crossref records and the published article body. The note records the measured light-shift gate fidelities by dimension, the quadratic scaling of gate error with qudit dimension, and the relevance of this empirical curve to the dimensional-advantage crossover parameter in qudit benchmarking.",
