Lesson 125: Shot noise vs decoherence slicing
Focus
Assume every diagram must map to topology and basis gates—not textbook abstractions alone. Token Shot noise vs decoherence slicing:125 keeps neighbouring lessons differentiable.
Key ideas
- Thread: Shot noise vs decoherence slicing · drill v5 · spin
460123. - 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.
