Calibration Data and Provenance
Use QDash's data views to move from a chip-wide health check to one measurement and the values it produced.

| Question | Open |
|---|---|
| Is the chip broadly healthy? | Dashboard |
| How does one metric compare across targets? | Metrics |
| What is the latest result for a task on each target? | Chip |
| How did parameters change over time? | Analysis |
| Which result produced a value, and what depends on it? | Lineage on the result or metric |
| What happened in one run? | Execution or Task Results |
The active project, chip, time range, cool-down, target direction, and value selection determine what these pages show. Include that scope when sharing an observation.
Scan Current State
- Open Dashboard and select a chip.
- Set the time range or cool-down and choose the latest, best, or average value selection.
- Review coverage and distributions, then select a metric or target that needs investigation.
Open Metrics when one parameter across many targets is the focus. For coupling data, confirm the displayed direction before comparing values. Narrow the Color range above the topology when an outlier flattens the other colors; the range is shared with Dashboard and described in Dashboard.
Inspect Measurements
Open Chip and select a task to see its latest results on the topology. Select a qubit or coupling to open its history and artifacts. Use Task Results to search across executions by chip, task, target, or status.
Figures and raw data are available only when the selected task produced them.
Follow Parameter History
Open Analysis to compare selected parameters over time. If a chart is empty, broaden the time range and confirm the chip, target, and parameter selections.
Open Lineage on a task result, on an entry in a metric's history, or on a row of an execution's Parameter changes to see which task produced the value, the current values that task read, and the values derived from it. Manual edits and seed imports appear as the producer of the values they wrote. After changing a value, re-run the tasks that produced the values derived from it. Full graph shows every value the selected one derives from.
Modify Current Parameters
Use Calibration DB to review current values, modify YAML candidates, or remove an invalid current value:
- Open Calibration DB and select Modify parameters.
- Compare the YAML candidate values with the current database.
- To change a value, select the parameters to import and edit them if needed.
- Review the proposed changes, then confirm the import.
- To remove a current value, select Edit import value, then select Delete and confirm the deletion.
The modification view shows only parameters the deployment permits. Frequency values produced by calibration experiments can be excluded from seed import even when a YAML file contains them. Treat the comparison as a review, not as an unconditional overwrite.
