To address this, the authors introduce an approach that facilitates the establishment of paths capable of delivering end-to-end fidelity above a specified threshold, without requiring detailed knowledge of the quantum network's properties. In this study, the authors define algorithms that are specific instances of this approach and evaluate them in comparison to Dijkstra's shortest path algorithm and a fully knowledge-aware algorithm through simulations. The authors’ results demonstrate that one of the proposed algorithms consistently outperforms the other methods in delivering paths above the fidelity threshold, across various network topologies and the number of source-destination pairs involved, while maintaining significant levels of fairness among the users and being robust to inaccurate estimations of the expected end-to-end fidelity.</p>","PeriodicalId":100651,"journal":{"name":"IET Quantum Communication","volume":"6 1","pages":""},"PeriodicalIF":2.8,"publicationDate":"2025-02-25","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://onlinelibrary.wiley.com/doi/epdf/10.1049/qtc2.70000","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143481376","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Despite these benefits, their implementation has been constrained by challenges in generation, transmission, and detection. This paper presents a novel theoretical framework for transmitting quantum information using qudit entanglement distribution over a superposition of causal orders in two quantum channels. Using this model, a quantum switch operation for 2-qudit systems is introduced, which facilitates enhanced fidelity of entanglement distribution and quantum teleportation. The results demonstrate that the use of qudits in entanglement distribution achieves a fidelity improvement from 0.5 (for qubit-based systems) to 0.94 for 20-dimensional qudits, even under noisy channel conditions. This enhancement is achieved by exploiting the increased Hilbert space of high-dimensional states and the inherent noise-resilience properties of quantum switches operating in superpositions of causal orders. The findings underscore the potential of qudit-based quantum systems in achieving robust and high-fidelity communication in environments where traditional qubit-based systems face limitations.</p>","PeriodicalId":100651,"journal":{"name":"IET Quantum Communication","volume":"6 1","pages":""},"PeriodicalIF":2.8,"publicationDate":"2025-01-24","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://onlinelibrary.wiley.com/doi/epdf/10.1049/qtc2.12122","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143118771","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

A veto means that when the voting council puts forward a proposal, it cannot pass unless all the voters agree to it.

In most existing quantum anonymous one-vote veto voting protocols, an absolutely honest third party is generally required to assist the voting. However, it is difficult to find a fully trusted third party in reality. In addition, the existing quantum anonymous one-vote veto protocol does not consider the attack from the insider voters.
