L0 · Declined / unavailable
The system could not produce a claim. No evidence should be inferred.
Evidence standard
Separate quantum proof from quantum theatre.
Advay reports classify what is simulated, projected, stitched, measured and independently reproduced so stakeholders can evaluate claims without ambiguity.
Evidence ladder
The label matters as much as the number.
This ladder is embedded into Advay reports and is used to prevent projection, stitched composition and measured hardware evidence from being mixed together.
L1 · Static or ideal simulation
Parser, compiler, gate-count or ideal simulator output. Useful, but not physical evidence.
L2 · Noisy simulation / projection
A noise model or projected fallback. Must be labelled as projected when measurement is unavailable.
L3 · Stitched composition
A composed result using measured/static sub-results plus disclosed formulas or profile assumptions.
L4 · Measured device evidence
Data from a real device, decoder run or calibrated experiment with bounds and provenance.
L5 · Measured tile / logical evidence
Multi-qubit tile or QEC-relevant evidence that shows repeatability and error trend.
L6 · Independently reproduced
Evidence reproduced by an external lab, partner or reviewer under a controlled protocol.
Operating rules
How Advay prevents overclaiming.
No hidden upgrades
A metric cannot inherit a stronger evidence label from a different component.
Measured means measured
If measured LER was requested and unavailable, the output must say so visibly.
Per-field badges
Every resource, noise and success metric carries its own evidence classification.
Claims boundary first
Large-scale architecture modelling is not described as arbitrary full-state simulation.
Use the standard to evaluate your own quantum roadmap.
The evidence standard is useful for grant review, institutional planning, partner diligence and internal technology governance.
