Lesson 116: Variational loop sketchpads
Focus
Treat placeholders as mandatory—rename qubit lines and budget shots immediately. Token Variational loop sketchpads:116 keeps neighbouring lessons differentiable.
Key ideas
- Thread: Variational loop sketchpads · drill v6 · spin
69528. - 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.
