Deterministic quantum error-correction software, replayable evidence, and classical syndrome-transport experiments. QEC combines exact finite-code models with canonical JSON / SHA-256 receipts and validators that reconstruct results.
Current release line: v177.1
Includes sparse qutrit construction and opt-in CSS / syndrome-delivery research.
See the release history for changes and
verification records. Release labels and contract milestones are separate from
Python package metadata, which currently remains 173.0.0.
Open the browser-native Qutrit Harmonic Lab or Ququart Evidence Lab. For local/offline use, open the Qutrit lab or follow the Acoustic Lab guide. The hosted Ququart lab includes generated evidence that is not bundled in a fresh checkout.
Requires Python 3.10+ and Git. From a terminal on Linux or macOS:
git clone https://github.com/QSOLKCB/QEC.git
cd QEC
python -m venv .venv
. .venv/bin/activate
python -m pip install -e '.[dev]'
qec-qutrit
python scripts/generate_qec_research_evidence.py --checkOn Windows, activate with .venv\Scripts\Activate.ps1 in PowerShell.
qec-qutrit prints an exact bounded-error certificate; the research check verifies
the retained synthetic fixture. See installation and troubleshooting
for additional dependencies, and Rust TUI usage for the operator UI.
For the optional Rust TUI launcher, review the installer before running:
sh tui/install.shpython -m pytest -qOptional scientific/external backends may be skipped unless their extras are
installed. Use python -m pytest -q -ra to inspect skips; see
validation boundaries.
- Exact qutrit and ququart models: finite-code correction and FER evidence. Qutrit · Ququart
- Replayable receipts: canonical artifacts, source-bound claims, replication checks and decoder-governance boundaries. System documentation
- Six classical switching models: Strowger, Panel, Crossbar, ESS, digital TDM and packet routing, with cross-era replay. Contracts
- Acoustic syndrome transport: sampled classical waveforms, receiver checks and exact-model correction. Bridge and limits
- Opt-in research: binary CSS presentation witnesses and synthetic delivery replay using an unchanged reference decoder. Scope and reproduction
- Qutrit circuit conformance: pinned prime-field SUM/SWAP and toric-code fixtures, independently replayed against GF(3) algebra. Donor and limits
These are bounded software models and experiments. They do not establish physical fault tolerance, hardware thresholds, quantum-state transfer, or quantum advantage. Hashes bind declared bytes; they do not by themselves prove authenticity or scientific correctness. Governance receipts do not activate a decoder. QEC OS runtime/benchmark work remains deferred to v193.x; see the roadmap.
