Reproducible quantum-many-body study of digital statistical-phase transport in a number-conserving correlated-hopping SSH ladder, using exact diagonalization.

ANTLER stands for Anyonic Numerical Transport for Logical Exchange and Robustness. It names the research program: numerical transport in a correlated-hopping ladder, logical exchange protocols and quantitative robustness tests. The name describes the motivation of the model, not a claim that physical anyons or non-Abelian braiding have been demonstrated.

This public release contains the validated Abelian digital phase primitive, the Phase 0 to 4.7 audit trail used to establish it, and the separately curated Phase 5 to 8 research archive. It does not claim non-Abelian braiding, universality, fault tolerance, or a topological quantum computer.

For the digital protocol, the all-fine-step data at dt=0.125 and D=4,6,8,10,12 fit

odd_slope(D) = -1 + 0.66493 D^(-2.28624)

with R^2 = 0.999983. All retained points have leakage below 5e-5 and minimum singular value above 0.999975.

• paper/: LaTeX manuscript, figures and bibliography for the Abelian paper.

The observed ANTLER gate family is Abelian. The public data support a controlled logical phase primitive in the specified model only. They do not establish a physical anyon platform or non-Abelian topological computation. The Phase 5 to 8 archive records scoped negative results, external controls and an explicit neutral-link extension contract. Its claim boundary is in docs/public/PHASE5_8_RESEARCH_ARCHIVE.md.
