Lesson 123: Shot noise vs decoherence slicing
Focus
Treat placeholders as mandatory—rename qubit lines and budget shots immediately. Token Shot noise vs decoherence slicing:123 keeps neighbouring lessons differentiable.
Key ideas
- Thread: Shot noise vs decoherence slicing · drill v3 · spin
508931. - 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.
