System Overview

Objective

LiDMaS+ provides reproducible logical-error studies for quantum error correction (QEC), with two primary goals:

  1. Produce deterministic threshold and scaling artifacts from controlled experiment scripts.
  2. Keep open execution surfaces equivalent at artifact level (same manifests/tables/plots when configuration is matched).

Scope

In scope:

  • Surface-code and hybrid CV/discrete replay pipelines.
  • Decoder matrix comparison (mwpm, uf, bp, optional neural_mwpm).
  • Paper workflow orchestration (examples/paper_runs/*), including paper_04.

Out of scope:

  • Formal proof assistant verification.
  • Hardware-specific physical calibration guarantees.

Core Solution Surfaces

  • Simulation/decoding engine: C++ modules under src/.
  • Experiment orchestration: shell + Python in examples/.
  • Enterprise application stack: maintained in a private track outside this OSS release surface.
  • Data products: CSV/Markdown/PNG/PDF artifacts in examples/results/ and examples/paper_runs/*/results/.

Trust Model

The project increases trust through:

  • deterministic seed controls,
  • explicit manifest outputs,
  • script-by-script traceability to mathematical quantities,
  • parity checks between execution surfaces.
