Quantum AI Basic — 011: reconcile noisy simulators vs device traces on `Two-qubit basis and CNOT scaffolding` — memo `402864 [11]`

Lesson 011: Two-qubit basis and CNOT scaffolding

Focus

Bias toward repeatable experiment notebooks: circuits, mitigation settings, timestamps. Token Two-qubit basis and CNOT scaffolding:11 keeps neighbouring lessons differentiable.

Key ideas

• Thread: Two-qubit basis and CNOT scaffolding · drill v1 · spin 15386.
• 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.

Transpilation checklist

- [ ] basis translation logged for `rz-sx vs native`
- [ ] SWAP count vs manual estimate delta noted
- [ ] layout seed `S-235`
