(2022)</a>. </div> <div class="abstract">Summary: With the development of quantum computer, the research of quantum key distribution (QKD) protocols and high-dimensional quantum key distribution (HD-QKD) protocols has emerged as an important subject. Most of the existing QKD protocols are based on complex physical devices or have high technical requirements for users. Hadamard gate can realize the interconversion of mutually unbiased bases (MUB) and have advantages in the QKD protocol construction. In this paper, we propose a ternary quantum key distribution protocol using three-dimensional Hadamard gate. This protocol can enrich the research of high-dimensional key distribution protocols. The protocol can directly send and receive ternary quantum with security and efficiency. By logic tree analysis, the protocol is demonstrated to show higher security than the two-dimensional protocol in a perfect channel. In principle, this protocol could be extended to higher dimensions and would benefit the research of high-dimensional key distribution protocols.</div> <div class="clear"></div> <br> <div class="citations"><div class="clear"><a href="/?q=rf%3A7489104">Cited in <strong>1</strong> Document</a></div></div> <div class="classification"> <h3>MSC:</h3> <table><tr> <td> <a class="mono" href="/classification/?q=cc%3A81P94" title="MSC2020">81P94</a> </td> <td class="space"> Quantum cryptography (quantum-theoretic aspects) </td> </tr><tr> <td> <a class="mono" href="/classification/?q=cc%3A94A60" title="MSC2020">94A60</a> </td> <td class="space"> Cryptography </td> </tr><tr> <td> <a class="mono" href="/classification/?q=cc%3A81P10" title="MSC2020">81P10</a> </td> <td class="space"> Logical foundations of quantum mechanics; quantum logic (quantum-theoretic aspects) </td> </tr><tr> <td> <a class="mono" href="/classification/?q=cc%3A68P25" title="MSC2020">68P25</a> </td> <td class="space"> Data encryption (aspects in computer science) </td> </tr><tr> <td> <a class="mono" href="/classification/?q=cc%3A81P68" title="MSC2020">81P68</a> </td> <td class="space"> Quantum computation </td> </tr><tr> <td> <a class="mono" href="/classification/?q=cc%3A81P70" title="MSC2020">81P70</a> </td> <td class="space"> Quantum coding (general) </td> </tr><tr> <td> <a class="mono" href="/classification/?q=cc%3A05B20" title="MSC2020">05B20</a> </td> <td class="space"> Combinatorial aspects of matrices (incidence, Hadamard, etc.) </td> </tr><tr> <td> <a class="mono" href="/classification/?q=cc%3A15B34" title="MSC2020">15B34</a> </td> <td class="space"> Boolean and Hadamard matrices </td> </tr><tr> <td> <a class="mono" href="/classification/?q=cc%3A81P55" title="MSC2020">81P55</a> </td> <td class="space"> Special bases (entangled, mutual unbiased, etc.) </td> </tr><tr> <td> <a class="mono" href="/classification/?q=cc%3A05C05" title="MSC2020">05C05</a> </td> <td class="space"> Trees </td> </tr></table> </div><div class="keywords"> <h3>Keywords:</h3><a href="/?q=ut%3AHD-QKD">HD-QKD</a>; <a href="/?q=ut%3Aternary+quantum">ternary quantum</a>; <a href="/?q=ut%3AHadamard+gate">Hadamard gate</a></div>  <div class="modal fade" id="metadataModal" tabindex="-1" role="dialog" aria-labelledby="myModalLabel"> <div class="modal-dialog" role="document"> <div class="modal-content"> <div class="modal-header"> <button type="button" class="close" data-dismiss="modal" aria-label="Close"><span aria-hidden="true">×</span></button> <h4 class="modal-title" id="myModalLabel">Cite</h4> </div> <div class="modal-body"> <div class="form-group"> <label for="select-output" class="control-label">Format</label> <select id="select-output" class="form-control" aria-label="Select Metadata format"></select> </div> <div class="form-group"> <label for="metadataText" class="control-label">Result</label> <textarea class="form-control" id="metadataText" rows="10" style="min-width: 100%;max-width: 100%"></textarea> </div> <div id="metadata-alert" class="alert alert-danger" role="alert" style="display: none;">  </div> </div> <div class="modal-footer"> <button type="button" class="btn btn-primary" onclick="copyMetadata()">Copy to clipboard</button> <button type="button" class="btn btn-default" data-dismiss="modal">Close</button> </div> </div> </div> </div> <div class="functions clearfix"> <div class="function">  <a type="button" class="btn btn-default btn-xs pdf" data-toggle="modal" data-target="#metadataModal" data-itemtype="Zbl" data-itemname="Zbl 1486.81074" data-ciurl="/ci/07489104" data-biburl="/bibtex/07489104.bib" data-amsurl="/amsrefs/07489104.bib" data-xmlurl="/xml/07489104.xml" > Cite </a> <a class="btn btn-default btn-xs pdf" data-container="body" type="button" href="/pdf/07489104.pdf" title="Zbl 1486.81074 as PDF">Review PDF</a> </div> <div class="fulltexts"> <span class="fulltext">Full Text:</span> <a class="btn btn-default btn-xs" type="button" href="https://doi.org/10.1007/s10773-022-05041-w" aria-label="DOI for “Ternary quantum key distribution protocol based on Hadamard gate”" title="10.1007/s10773-022-05041-w">DOI</a> </div> <div class="sfx" style="float: right;"> </div> </div> <div class="references"> <h3>References:</h3> <table><tr> <td>[1]</td> <td class="space">Zbinden, H.; Bechmann-Pasquinucci, H.; Gisin, N.; Ribordy, G., Quantum cryptography, Appl.
