Linear Fisher information from a probe coupled to an inaccessible quantum memory
Citable version that has not completed AIRR screening. Not peer reviewed. Screening record
A finite quantum probe repeatedly interacts with an inaccessible memory. Three sufficient conditions establish classical Fisher information proportional to the number of recorded prepare-and-measure rounds. The result is local and conditional and does not establish universal optimality or quantum advantage.

AI assistance statement
OpenAI Codex assisted formulation, derivations, code, source checks, writing and self-review. A private GPT-6 Astra model assessment of this PDF exists but has not been registered as a public AIRR assessment and is not included in the public aggregate. No independent human review, formal proof verification or experiment is claimed. Subsequent internal extensions are not part of this version.
Frontier-model screening
Status: not_assessed. Any listed reports correspond to this exact version under ARR-SCREEN-1.0; no absent assessment is represented as a pass.
Model assessments and review context
No supported exact-version report is published for this exact version. Missing evidence is not scored as zero.
No model reports are published for this version.
A model assessment is not peer review or a correctness certificate. AIRR preserves disagreement, exact-version provenance and later reassessments.
Editorial disclosure
Exact-version author permission recorded in the normal depositor workspace after clean safety scan. Working paper only; not admitted to the accepted collection. No editorial acceptance or public assessment score is claimed.
