Quantum AI Intermediate — 132: reconcile noisy simulators vs device traces on `Cost models for QPUs` — memo `148937 [132]`

Lesson 132: Cost models for QPUs

Focus

Document classical post-processing: it often dominates wall-clock and interpretability. Token Cost models for QPUs:132 keeps neighbouring lessons differentiable.

Key ideas

• Thread: Cost models for QPUs · drill v2 · spin 612088.
• 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.
