Quantum AI Advanced — 094: pair classical optimizers with job IDs on `Cross-vendor fidelity comparisons` — memo `556070 [94]`

Lesson 094: Cross-vendor fidelity comparisons

Focus

Bias toward repeatable experiment notebooks: circuits, mitigation settings, timestamps. Token Cross-vendor fidelity comparisons:94 keeps neighbouring lessons differentiable.

Key ideas

• Thread: Cross-vendor fidelity comparisons · drill v4 · spin 882341.
• 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.

1. Target CI width `0.075` @ confidence `96`
2. Pilot shots `1024` expanding to `7701` if variance plateaus
3. Telemetry fields `job_id,device_tz,mitigation_bundle`
4. Stop rule `halt if RB infidelity > 0.002083`
