Read beyond the abstract

Our research notes separate reported results from interpretation, and explain what to check before comparing claims.

• Below threshold: what a surface-code memory proves

  Increasing code distance can improve a logical memory while leaving important computational capabilities untested. Use the measured task, denominator, and decoder conditions to assess the claim.

• 48 logical qubits: read the acceptance conditions too

  A logical-qubit count becomes informative when paired with encoding, circuit, evaluation metric, and retained trials. This note offers a worksheet for comparing demonstrations with different selection conditions.

• Better than physical: which circuit is the baseline?

  An improvement factor needs its physical baseline and selection rule. Use this paper to practice comparing an encoded circuit with the actual unencoded task, rather than a headline gate fidelity.
