Underwater Quantum Communications 2019

Dear Colleagues,

Quantum information science has emerged as an important scientific undertaking that promises to transfigure certain components of our information infrastructure. Certain quantum information devices for improved communication and computation are finally taking shape and becoming a reality. For example, China recently deployed a satellite that is able to conduct free-space quantum key distribution experiments between two ground sites. Additionally, D-Wave, IBM, and Google have developed early prototypes for diverse forms of quantum computation.

At the same time, underwater communications are of crucial importance to many of the world’s naval forces. Indeed, it is critical to have a robust and secure communication system that is able to connect ground stations and underwater vehicles on long seaborne missions. However, RF and acoustic channels have severe limitations. For instance, underwater RF communications can only be accomplished with ELF or VLF frequencies, which require cumbersome receiving and transmitting antennas. Additionally, the acoustic channel is a non-stealthy means of communication.

Thus, it is only natural to explore the potential applications of quantum communications in the underwater environment. This is the reason why this Special Issue of Applied Sciences intends to provide a wide and comprehensive view of the theory, experiments, computational problems, potential applications, and challenges in the area of underwater quantum communications. Clearly, a major point of interest is the potential use of entanglement, squeezed states, and other quantum properties to increase the range, stealth, and capacity of underwater communications channels.

We are looking for original research or state-of-the-art review papers in areas associated with underwater quantum communications.

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. 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.
