Special Issue Information

Dear Colleagues,

Information is the currency of the modern age. Security of information will continue to be of paramount importance in the foreseeable future. Quantum communication, in no doubt currently the most mature field within the vast domain of quantum information science developed during the past three decades that combines quantum physics and information theory, provides unconditional secure information transmission based on the physical laws of nature. Its security is guaranteed even under the attack of an eavesdropper with the most powerful supercomputer including a universal quantum computer that is yet to be built, in contrast to its classical counterpart.

Quantum key distribution (QKD), an approach for creating shared cryptographic keys that can be used to encrypt and decrypt data, has its security foundation established rigorously and theoretically. On the practical side, free space or fibre-based QKD experiments have already been demonstrated for distances over a few hundred kilometres. The recent work of distributing entangled photons for a distance over 1000 km further lays the groundwork for future intercontinental QKD experiments. Commercial products from several companies worldwide have been available and new start-ups are emerging. Despite these developments, the field of QKD, and more generally quantum communication, is still actively evolving. New ideas are coming up and the related technologies are being perfected. These include deterministic light sources (single photon / entangled photons) with high efficiencies, high speed and low cost photon detectors, more efficient quantum memories and quantum repeaters, QKD protocols that are not prone to hacking over imperfect devices, multiple alphabet schemes employing the orbital angular momentum degree of photons, direct quantum communication for high speed data transmission, etc.

This Special Issue aims to present the cutting-edge research in the field of quantum communication technologies spanning from the fundamental theories of quantum communication channel, new protocols and security analysis, to the experimental demonstrations of these protocols and the advancement of photonic devices for quantum communication. Comprehensive reviews of the latest achievements of these topics are also encouraged.

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. Technologies is an international peer-reviewed open access quarterly 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 350 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.
