Day 12 — Papers 06 & 07

Debrief

Fill this in the evening of Sat Sep 19. Tomorrow is the last day with any slack in it; Day 14 is dress rehearsals only.


Scores

Paper Score /34 % Pass (24)? Time used
Paper 06 /45 min
Paper 07 /45 min

Full trend — 01: ___ · 02: ___ · 03: ___ · 04: ___ · 05: ___ · 06: ___ · 07: ___

Is the line going up? A flat line across seven papers is the single most important signal you have, and it means Day 13 should be consolidation, not Paper 08.

Misses by section

Count every wrong answer — and every right answer you were not sure of — against the section it came from.

§ Section Wrong Unsure
1 Create quantum circuits (18%)
2 Perform quantum operations (16%)
3 Run quantum circuits (15%)
4 Sampler primitive (12%)
5 Estimator primitive (12%)
6 Visualization (11%)
7 Retrieve and analyze results (10%)
8 OpenQASM (6%)

Miss log

One row per wrong answer. The third column is the one that matters.

Q What the answer was Why my answer looked right

Trap check

Tick any that caused a miss today.

  • Little-endian bit ordering (counts keys, Pauli labels, qubit indices)
  • Sampler needs measurements; Estimator must not have them
  • Observables need apply_layout after transpilation
  • Primitives require ISA circuits — untranspiled circuits are rejected
  • resilience_level is 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_multivector shows a zero vector

Top 3 weak topics

Be specific — "Estimator" is not a topic, "ZNE noise_factors vs extrapolator" is.

Day 13 decision

Day 13 is Paper 08 plus consolidation. Based on today, which gets the morning?

  • Paper 08 as planned — the trend is up and pacing is comfortable
  • Consolidation first, Paper 08 only if time allows — the trend is flat, or §6/§8 went badly, or you ran out of time on either paper
