Quantum AI Intermediate — 072: pair classical optimizers with job IDs on `Post-processing inversion checks` — memo `167303 [72]`

Lesson 072: Post-processing inversion checks

Focus

Prefer falsifiable hypotheses (shot count, fidelity floor) over buzzword proofs-of-concepts. Token Post-processing inversion checks:72 keeps neighbouring lessons differentiable.

Key ideas

• Thread: Post-processing inversion checks · drill v2 · spin 380391.
• 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.
