Specifically, in the quantum secure direct communication network, part of the key establishment process is replaced by the verification of signatures encoded in quantum states. This approach not only achieves access authentication but also effectively resists DoS attacks. We provide a detailed security analysis of our protocol.

In this work, we study the thermodynamics of a quantum channel that erases an arbitrary state of a qubit memory in contact with a reservoir composed of a thermal qubit and a pure ancilla qubit. The channel is based only on CNOT gates, and the introduction of the ancilla makes it capable of operating beyond Landauer’s limit, when the temperature of the thermal qubit is above a given limit temperature. However, we observe that, since the introduction of the ancilla does not correspond to a strict Landauer’s scenario, our protocol does not represent a violation of Landauer’s principle.</p></div>","PeriodicalId":746,"journal":{"name":"Quantum Information Processing","volume":"24 5","pages":""},"PeriodicalIF":2.2,"publicationDate":"2025-05-20","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144091186","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"物理与天体物理","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
