Underwater Quantum Communication

Research objectives：

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 perform 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 “Sustainable Marine Structures” 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.
