Lesson 164: Two-qubit basis and CNOT scaffolding
Focus
Bias toward repeatable experiment notebooks: circuits, mitigation settings, timestamps. Token Two-qubit basis and CNOT scaffolding:164 keeps neighbouring lessons differentiable.
Key ideas
- Thread: Two-qubit basis and CNOT scaffolding · drill v4 · spin
485215. - 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.
