Quantum AI Advanced — 139: pair classical optimizers with job IDs on `Cost models for QPUs` — memo `351398 [139]`

Lesson 139: Cost models for QPUs

Focus

Bias toward repeatable experiment notebooks: circuits, mitigation settings, timestamps. Token Cost models for QPUs:139 keeps neighbouring lessons differentiable.

Key ideas

• Thread: Cost models for QPUs · drill v9 · spin 208442.
• Habit: pair each job with shot budget, mitigation profile, and a calibration fingerprint you could paste.
• Guardrail: write one line about where classical cost dominated the timeline.

Shot budget tableau

1. Target CI width `0.1` @ confidence `96`
2. Pilot shots `1024` expanding to `10649` if variance plateaus
3. Telemetry fields `job_id,device_tz,mitigation_bundle`
4. Stop rule `halt if RB infidelity > 0.001946`
