Abstract

fetched live from OpenAlex

Ce memoire examine le rôle des fonctions à sens unique en cryptographie quantique. À cette fin, elle se penche sur les générateurs d’états quantiques pseudaléatoires, un concept récemment introduit par Ji, Liu et Song, qui sont analogues aux générateurs pseudaléatoires. Des travaux récents ont montré que ces générateurs peuvent être construits à partir de toute fonction à sens unique (sécurisée quantiquement) et peuvent être utilisés pour créer diverses primitives cryptographiques quantiques, telles que l’engagement de bit quantique, le chiffrement quantique à clé symétrique et les codes d’authentification de messages quantiques. Cela implique que, tout comme en cryptographie classique, les fonctions à sens unique constituent une condition suffisante pour réaliser la cryptographie quantique.Bien qu’elles soient suffisantes, elles ne sont peut-être pas strictement nécessaires. Des travaux novateurs, présentés par Kretschmer, ont montré qu’il existe certains mondes relativisés dans lesquels des générateurs d’états quantiques pseudaléatoires existent alors même que les fonctions à sens unique n’existent pas. Cela suggère que les générateurs d’états quantiques pseudaléatoires pourraient reposer sur des hypothèses plus faibles. Ainsi, même si la cryptographie classique s’avérait impossible, la cryptographie quantique ne le serait peut-être pas. Ce memoire présente un résumé complet de ces résultats, en mettant l’accent sur la clarté et la lisibilité, et discute des perspectives de recherche prometteuses

Not calibrated prevalence, not ground truth. Human validation pending. The Gemma side is a direct model label for every work in the frame, read from the title-only record. The Codex side is a classifier learned from the 10,348 direct Codex labels and calibrated to design-weighted sample rates; fields without enough sample support carry no Codex call. Candidate is the union of the two sides; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels.

Machine scores (provisional)

The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.

Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
