A new crate, wai/wai-quantum-py, built by maturin 1.15.0 into one abi3 wheel
per platform (pyo3 0.29.3, Python 3.9 on), module wai_quantum. Its extension
module wraps the shared job engine and nothing else: run, plan, lint, draw
(text and the engine SVG), layout, critique, improve, shortcuts,
equivalent, verify, seal, canonical, digest, methods, accuracy_classes and
history, values crossing one to one with JSON (NaN, integers past 64 bits
and non-string keys refused). A job is the service form as a plain dict
with helpers (counts, probabilities, expectations, amplitudes, method,
accuracy, receipt); Key reads and writes the command line key files and
finds the same user key; bloch gives each qubit reduced state from the
engine expectation values. A refusal raises EngineError with the engine
message, its line, and a code slot for the engine diagnostic codes.
Service is a client in the standard library alone for the job service
(submit, status, result, cancel, run), naming itself
wai-quantum-python/<version>, its receipts checked here offline.
Widgets (the widgets extra): Circuit (the engine drawing, gates clickable,
authorship marks from a history), Result, Receipt (the engine verdict) and
Bloch (drag to turn), each a plain ES module, each with static HTML (and
SVG) fallbacks that render without the widget library.
Five doc notebooks run in CI and are held to their stored outputs.
ci/check.sh is the whole check; 62 pytest tests hold the package to the
command line (same results, plans, lints, critiques, drawings, methods,
equivalence verdicts; receipts verified both ways; the same user key; the
digest recomputed from Python canonical bytes), to the service run locally,
and run the front ends under node on the payloads; Python 3.9 smoke with
the wheel alone. Workflow wai-quantum-py.yml runs it on linux and macos.
