Advances in Quantum Secure Communications

Dear Colleagues,

In recent years, information security has become a widely discussed topic following the rapid development and the vast progress of network technology. Furthermore, with the development of quantum technology, the security of classical cryptographic schemes based on computational complexity will face serious threats in the future. However, using quantum physics to process information and building a network with quantum nature in a connected world has many positive effects. Quantum computers offer algorithm speedups, which are advantageous in interdisciplinary fields such as machine learning. Quantum secure communication, especially quantum cryptography protocol based on the principles of quantum mechanics, is unconditionally secure in theory, and it has already attracted the attention of many researchers. At present, quantum cryptography protocol has made significant breakthroughs, such as quantum key distribution (QKD), quantum key agreement (QKA), quantum secure direct communication (QSDC), and so on. This Special Issue focuses on advances in quantum secure communications for electronics, especially the several popular quantum cryptographic protocols that researchers are currently concerned about. In this Special Issue, original research articles and reviews are welcome. Its scope  includes, but is not limited to, the following:

• quantum secure direct communication (QSDC);
• quantum private comparison (QPC) ;
• quantum private query (QPQ);
• anonymous quantum communication (AQC);
• quantum identity authentication (QIA);
• quantum secret sharing (QSS);
• measurement-device-independent quantum key distribution (MDI-QKD);
• semi-quantum key agreement (SQKA);
• mutual authentication quantum key agreement (MAQKA);
• controlled quantum key agreement (CQKA);
• quantum conference key agreement (QCKA).

We look forward to receiving your contributions.

Manuscript Submission Information

Manuscripts should be submitted online at mdpi.longhoe.net by registering and logging in to this website. Once you are registered, click here to go to the submission form. Manuscripts can be submitted until the deadline. All submissions that pass pre-check are peer-reviewed. Accepted papers will be published continuously in the journal (as soon as accepted) and will be listed together on the special issue website. Research articles, review articles as well as short communications are invited. For planned papers, a title and short abstract (about 100 words) can be sent to the Editorial Office for announcement on this website.

Submitted manuscripts should not have been published previously, nor be under consideration for publication elsewhere (except conference proceedings papers). All manuscripts are thoroughly refereed through a single-blind peer-review process. A guide for authors and other relevant information for submission of manuscripts is available on the Instructions for Authors page. Electronics is an international peer-reviewed open access semimonthly journal published by MDPI.

Please visit the Instructions for Authors page before submitting a manuscript. The Article Processing Charge (APC) for publication in this open access journal is 2400 CHF (Swiss Francs). Submitted papers should be well formatted and use good English. Authors may use MDPI's English editing service prior to publication or during author revisions.
