Lesson 165: Two-qubit basis and CNOT scaffolding
Focus
Treat placeholders as mandatory—rename qubit lines and budget shots immediately. Token Two-qubit basis and CNOT scaffolding:165 keeps neighbouring lessons differentiable.
Key ideas
- Thread: Two-qubit basis and CNOT scaffolding · drill v5 · spin
704443. - 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.
