scpn-quantum-control — Changelog

Changelog

All notable changes to scpn-quantum-control are documented here. Format follows Keep a Changelog.

Full detailed changelog: CHANGELOG.md

[0.7.0] - 2026-03-02

Packaging, RNG hygiene, CI, exports hardening.

  • Fix crypto __all__ (callable symbols, not module names)
  • PEP 561 py.typed marker
  • Seeded RNG in QuantumDenseLayer, inf → nan in PhaseVQE
  • Named constants in percolation, pip cache in CI, dependency upper bounds
  • 456 tests, 99%+ coverage

[0.6.4] - 2026-03-01

Docs/metadata hardening.

  • Fix stale test counts (411/424 → 442) in docs pages
  • Fix header generator version string (v0.5.1 → v0.6.3)
  • Complete README architecture tree (3 missing files)
  • Add scpn-phase-orchestrator to Related Repositories
  • Update SECURITY.md supported versions (0.6.x)
  • Add pip ecosystem to dependabot
  • Version bump 0.6.2 → 0.6.4

[0.6.3] - 2026-03-01

Coverage gate, mitigation API docs, notebook table.

  • Coverage gate in CI, mitigation API docs, notebook summary table, ruff fix
  • Test count: 424 → 442

[0.6.2] - 2026-03-01

Notebook fixes + Knm heatmap figure.

  • Notebooks 01/03/04: classical_kuramoto_ode → classical_kuramoto_reference
  • Notebook 03: ZNE scales [1,2,3,4,5] → [1,3,5,7,9] (odd required by gate_fold_circuit)
  • Notebook 04: rewrite to 8-qubit Trotter + 16-layer classical (16-qubit statevector intractable on laptop)
  • figures/generate_knm_heatmap.py + figures/knm_heatmap.png (16×16 K_nm coupling matrix)
  • Knm heatmap figure in README with annotated calibration anchors
  • All 4 notebooks executed with embedded outputs
  • Remove misplaced docs/SESSION_LOG and docs/HANDOVER (duplicates of .coordination/)

[0.6.1] - 2026-03-01

mypy + Zenodo metadata fixes.

  • mypy errors in bridge module: remove FloatArray type alias (incompatible with Python 3.9), fix Path(None) in control_plasma_knm.py
  • Zenodo metadata enriched (.zenodo.json, CITATION.cff)

[0.6.0] - 2026-03-01

Hardening + high-level API.

  • Input validation guards on all public API constructors — prevents div-by-zero in qlif, qsynapse, qstdp, qaoa_mpc, classical_kuramoto_reference; bounds-checks on bell_inequality_test, best_entanglement_path
  • PhaseVQE.solve() now returns exact_energy, energy_gap, relative_error_pct, n_params
  • Notebook 02 fixed to use enriched solve() dict
  • 13 validation tests (424 total)

[0.5.1] - 2026-03-01

Version alignment. Fixes __version__ mismatch from v0.5.0 tag timing.

[0.5.0] - 2026-03-01

Quantum cryptography hardware experiments.

  • 3 new crypto experiments: Bell test (CHSH), ZZ correlator, QKD QBER
  • devetak_winter_rate() key rate computation
  • 20 experiments in registry, 411 tests

[0.4.0] - 2026-02-28

Docs, notebooks, and test depth.

  • GitHub Pages MkDocs Material site (7 pages, auto-deploy)
  • 4 Jupyter notebooks: Kuramoto XY, VQE ground state, ZNE mitigation, UPDE-16
  • 10 new hardware experiments (noise baseline, 8-osc ZNE, Trotter order-2, etc.)
  • 14 property-based tests (hypothesis), 8 edge-case tests, 13 coverage-gap tests
  • 4 integration tests, 7 regression tests
  • Test count: 208 → 254

README rewrite and validation hardening.

  • Motivating abstract: SCPN→XY isomorphism, Kuramoto-to-Hamiltonian derivation, 4 figures
  • mypy expanded to 30 source files (8 module paths), zero errors
  • VALIDATION.md test count 88 → 199
  • Paper 27 citation, examples/README.md walkthrough

[0.2.0–0.2.7] - 2026-02-28
