(2023)</a>. </div> <div class="abstract">Summary: Continuous-variable measurement-device-independent quantum key distribution (CV-MDI QKD), whose core is Bell detection, can effectively resist attacks on the detection system. However, in CV-MDI QKD, Charlie is untrusted; the external environment will cause non-ideal Bell detection that will open security loopholes. We give a complete security analysis under non-ideal Bell detection caused by on-orthogonal measurement. The simulation results indicate that compared with no angle error, only $1^\circ$ angle error will cause the transmission distance to drop by 7 km. Therefore, our research further improves and perfects the security of CV-MDI QKD.</div> <div class="clear"></div> <br> <div class="citations"><div class="clear"><a href="/?q=rf%3A7695219">Cited in <strong>3</strong> Documents</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%3ACV-MDI+QKD">CV-MDI QKD</a>; <a href="/?q=ut%3Anon-ideal+Bell+detection">non-ideal Bell detection</a>; <a href="/?q=ut%3Aangle+error">angle error</a>; <a href="/?q=ut%3Asecret+key+rate">secret key rate</a>; <a href="/?q=ut%3Atransmission+distance">transmission distance</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 1542.81385" data-ciurl="/ci/07695219" data-biburl="/bibtex/07695219.bib" data-amsurl="/amsrefs/07695219.bib" data-xmlurl="/xml/07695219.xml" > Cite </a> <a class="btn btn-default btn-xs pdf" data-container="body" type="button" href="/pdf/07695219.pdf" title="Zbl 1542.81385 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/s11128-023-03993-4" aria-label="DOI for “Impact of non-orthogonal measurement in Bell detection on continuous-variable measurement-device-independent quantum key distribution”" title="10.1007/s11128-023-03993-4">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">Scarani, V.; Bechmann-Pasquinucci, H.; Cerf, NJ; Dušek, M.; Lütkenhaus, N.; Peev, M., The security of practical quantum key distribution, Rev.
