(2022)</a>. </div> <div class="abstract">Summary: Utilizing the advantage of decoherence-free (DF) states, two semi-quantum private comparison (SQPC) protocols against the collective-dephasing noise and collective-rotation noise are proposed, respectively. In the protocols, two semi-quantum parties (i.e. participants with limited quantum capabilities) can compare their secrets with the help of a semi-honest third party (TP). Some common outsider’s and insider’s attacks are also discussed. Moreover, the simulations of our protocols on the IBM Quantum Experience show that our protocols are not only robust under two collective noises, but also feasible under the current quantum technology.</div> <div class="clear"></div> <br> <div class="citations"><div class="clear"><a href="/?q=rf%3A7625448">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></table> </div><div class="keywords"> <h3>Keywords:</h3><a href="/?q=ut%3Asemi-quantum+private+comparison">semi-quantum private comparison</a>; <a href="/?q=ut%3Acollective+noise">collective noise</a>; <a href="/?q=ut%3Adecoherence-free+states">decoherence-free states</a>; <a href="/?q=ut%3AIBM+quantum+experience">IBM quantum experience</a></div> <!-- Modal used to show zbmath metadata in different output formats--> <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;"> <!-- alert for connection errors etc --> </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"> <!-- Button trigger metadata modal --> <a type="button" class="btn btn-default btn-xs pdf" data-toggle="modal" data-target="#metadataModal" data-itemtype="Zbl" data-itemname="Zbl 1508.81753" data-ciurl="/ci/07625448" data-biburl="/bibtex/07625448.bib" data-amsurl="/amsrefs/07625448.bib" data-xmlurl="/xml/07625448.xml" > Cite </a> <a class="btn btn-default btn-xs pdf" data-container="body" type="button" href="/pdf/07625448.pdf" title="Zbl 1508.81753 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/s11128-022-03444-6" aria-label="DOI for “Robust semi-quantum private comparison protocols against collective noises with decoherence-free states”" title="10.1007/s11128-022-03444-6">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">Yao, AC, Protocols for secure computations, FOCS, 82, 160-164 (1982)</td> </tr><tr> <td>[2]</td> <td class="space">Boudot, F., Schoenmakers, B., Traore, J.: A fair and efficient solution to the socialist millionaires’ problem.
