Quantum AI Basic — 111: reconcile noisy simulators vs device traces on `Variational loop sketchpads` — memo `520883 [111]`

Lesson 111: Variational loop sketchpads

Focus

Assume every diagram must map to topology and basis gates—not textbook abstractions alone. Token Variational loop sketchpads:111 keeps neighbouring lessons differentiable.

Key ideas

• Thread: Variational loop sketchpads · drill v1 · spin 612525.
• 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.

- [ ] basis translation logged for `rz-sx vs native`
- [ ] SWAP count vs manual estimate delta noted
- [ ] layout seed `S-1975`

Rollback triggers: CX depth > THRESH-151 OR queue SLA breach without mitigation flip.
