Trap check
- Little-endian bit ordering (counts keys, Pauli labels, qubit indices)
- Sampler needs measurements; Estimator must not have them
- Observables need
apply_layoutafter transpilation - Primitives require ISA circuits — untranspiled circuits are rejected
-
resilience_levelis Estimator-only -
data.<creg>naming — the attribute is the classical register's name - Suppression (DD, twirling) vs mitigation (ZNE, TREX, PEC)
- Optimization level semantics (0–3)
- Job vs batch vs session
- Entangled state ⇒
plot_bloch_multivectorshows a zero vector
Consolidation
- §7 — job lifecycle, statuses, result anatomy. Solid? What is still shaky?
- §8 — QASM3 dumps/loads, QASM2 interop, reading a program cold. Solid?
Cheatsheet pass
Anything on final-review-cheatsheet.md that read as new rather than as a
reminder. This list should be empty. If it is not, it is tonight's reading.
Logistics
- Appointment time confirmed
- Test-centre route / online-proctor system check done
- ID ready
- Two alarms set
Tomorrow
Papers 09 and 10, full length, 68 questions and 90 minutes each, pass mark 47. Morning paper and afternoon paper, both under strict conditions. Nothing else.
