Special Issue Information

Dear Colleagues,

The last three decades have seen quantum cryptography growing into a well-established and mature research field. Recent breakthroughs in quantum computation and the beginning of the quantum space race have highlighted the strategic importance of quantum cryptography.

The goal of this special issue is to provide an open forum to discuss advanced problems in quantum cryptography, from fundamental concepts to technological advances and experimental challenges.

We invite contribution of research and review papers on a broad range of topics, including but not limited to discrete and continuous-variable quantum key distribution, twin-field, device-independent, and measurement-device-independent quantum key distribution, attacks and countermeasures in quantum key distribution, quantum sources and detectors, quantum networks, quantum repeaters, random number generation, homomorphic encryption, and two-party cryptography.

Manuscript Submission Information

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 papers will be 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. Entropy is an international peer-reviewed open access monthly 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 1600 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.
