Recent Development and Application of Quantum Communication and Security Protocols, Volume II

Dear Colleagues,

Since the establishment of the famous BB84 quantum key distribution protocol, which overcomes the classical counterparts of general key agreement protocols, quantum communication schemes have become a central topic of research triggered by the second quantum revolution.

At present, quantum communication is one of the most prominent emerging quantum technologies, with new applications continually arising, such as the quantum internet, which will become a reality in the near future. To leverage this new reality, new applications of quantum communication are increasingly being developed. In particular, issues of security and privacy have arisen as crucial requirements in a vast number of different applications. While the challenge of secure communication, which is addressed by various key distribution schemes, is the most prominent issue within quantum cryptography, many other unresolved problems have recently attracted the attention of the scientific community. Quantum cryptography beyond key distribution, addressing privacy requirements, ranges from secure multiparty computations (private data mining, e-voting, etc.) to authentication, blind computation, contract signing protocols, secret sharing, etc. The number of novel applications that are more efficient regarding information transmission and require less-expensive resources is so vast that any attempt at a list would be at risk of being incomplete.

Therefore, theoretical as well as computational and experimental studies and papers on new developments and applications of quantum communications are all welcome in this Special Issue.

Manuscripts should be submitted online at www.mdpi.com 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 250 words) can be sent to the Editorial Office for assessment.

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. Applied Sciences 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.
