Lesson 014: Two-qubit basis and CNOT scaffolding
Focus
Separate statistical noise from calibration drift before claiming algorithm wins. Token Two-qubit basis and CNOT scaffolding:14 keeps neighbouring lessons differentiable.
Key ideas
- Thread: Two-qubit basis and CNOT scaffolding · drill v4 · spin
304392. - 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.
