Advances in Quantum Communication

Dear Colleagues,

Quantum communication is known to be one of the most advanced quantum technologies, relying on the methods of quantum optics and quantum information theory. It aims at conceptually new solutions for information transfer, encoding, retrieval, processing, or security using special properties of quantum states. During the past decade, quantum communication has flourished due to rapid theoretical and experimental progress and approached full scale and even the first industrial implementations. Despite these advancements, the dynamic field of quantum communication demands new developments toward higher efficiency, robustness, scalability, and usability. Longer communication distances using quantum repeaters or extra-terrestrial channels, higher communication rates employing multiplexing or enhanced state engineering and detection, device-independent quantum security immune to quantum hacking, networked applications by means of effective multipartite entanglement supplied with efficient quantum routing tools or transition beyond optical wavelengths are needed for full-scale realizations of quantum communication. These directions—at the frontier of applied research—are complemented by fundamental studies of properties of quantum states and their relation to the efficiency of quantum communication.

The aim of this Special Issue is to further stimulate progress in the field of quantum communication and to collect articles and short reviews contributing to the development of quantum communication using discrete- and continuous-variable as well as hybrid approaches. We welcome submissions on theoretical or experimental advancements in topics including but not limited to quantum-enhanced communication, entanglement distribution and swapping, quantum teleportation and cloning, quantum networking, routing of quantum information, quantum key distribution and hacking, sources and detectors for quantum communication, multi-partite quantum communication, covert quantum communication, quantum repeaters and quantum memories, full- and measurement-device-independent quantum communication, quantum channel capacities, quantum channel estimation and discrimination, quantum error correction, quantum illumination and imaging, optical and microwave quantum communication, satellite and deep-space quantum communication, and atmospheric or fiber-based quantum communication.

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 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. 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 2600 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.
