This work analyzes a raw-feedback QIA interface based on BB84 states and operating over an authenticated classical channel, where transcript integrity is protected but receiver feedback is public. First, we establish a no-feedback benchmark: direct impersonation reduces to binary discrimination of value-conditioned BB84 mixed states, for which unambiguous state discrimination is impossible and maximum-confidence discrimination gives no forced-response advantage over minimum-error discrimination. Second, we identify a transcript-conditioned leakage mechanism: when an adversary retains a quantum auxiliary system, public raw feedback can condition that system into a pure-state discrimination instance for basis-selection information. We quantify this leakage using guessing probability, conditional min-entropy, accessible information, and an information-disturbance tradeoff. Third, we separate leakage from exploitation: the leakage becomes an impersonation advantage only under implementation deviations such as key-block reuse, weak session binding, abort-handling failure, or overly permissive thresholds. These results yield conservative authentication-length and threshold conditions for noisy and lossy optical implementations.</p>\u0000 </div>","PeriodicalId":72073,"journal":{"name":"Advanced quantum technologies","volume":"9 8","pages":""},"PeriodicalIF":4.3,"publicationDate":"2026-08-06","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"148752871","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
