Measured evidence
Measured silicon, measured runtime and calibrated device campaigns retain their measurement provenance and uncertainty.
Open cross-vendor evidence layer
Grade quantum results by evidence, not by vendor.
Advay ingests external simulator, decoder and measured-device results and emits a portable Evidence-Graded Artifact that can be verified without trusting an Advay dashboard session.
Canonical taxonomy
One vocabulary across platform, twin and external results.
The standard preserves detailed evidence labels while mapping them to one versioned rank model for conservative comparison.
Composed evidence
Claims derived from measured, EM, fabrication, Hamiltonian or profile inputs are labelled as stitched composition rather than direct measurement.
Simulation and projection
Aer, Stim/PyMatching, analytic formulas, Monte Carlo models and extrapolations are identified by their actual method and evidence strength.
Unavailable / declined
When an input or capability is missing, the system emits an explicit declined classification instead of silently upgrading the claim.
Operating rules
The verifier checks more than a signature.
Weakest-input propagation
A derived quantity cannot receive a stronger evidence grade than its weakest dependency.
Per-value provenance DAG
Every scalar claim can reference the inputs, method and source that produced it.
Canonical signed artifact
The EGA is canonicalised, SHA-256 sealed, optionally chained to a predecessor and signed with Ed25519.
Conflict-of-interest disclosure
Certification requires an explicit independent, related-party or self-certification declaration.
Artifact lifecycle
Ingest → grade → certify → verify.
- Ingest: normalize Aer counts, Stim/PyMatching decode outputs or measured campaigns.
- Grade: classify each value and construct its provenance graph.
- Certify: disclose COI, seal the content hash, link the certificate chain and sign.
- Verify: validate schema, hash, provenance constraints and signature through the public verifier.
Evaluate results from your own quantum stack.
Use the authenticated evidence lab to create an EGA, then share its public verification URL with reviewers, partners or institutions.
