Lesson 129: 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:129 keeps neighbouring lessons differentiable.

- Guardrail: write one line about where classical cost dominated the timeline.
