Special Issue Information
Dear Colleagues,
As a natural development of quantum information science, research on quantum communication, quantum radar, and quantum cryptography has been actively conducted in the field of physics and various principles have been proposed. However, at present, in the actual application environment, the research to date has not contributed to the realization of systemic devices that surpass conventional functions. Therefore, the research and development of quantum technology from an engineering and technology perspective are necessitated. In the first volume of this Special Issue, we were able to include pioneering papers reflecting research in which quantum effects outperform conventional technologies in real environments. The second volume of this Special Issue provides an opportunity for a discussion that will promote specific research on the aforementioned quantum techniques, which are effective even in poor environments. Through these two volumes, we can expect quantum communication to further expand the possibilities of ultrahigh-speed optical communication, for quantum radar to make all-weather sensors feasible, and for macroscopic quantum cryptography to contribute to enhancing the security of the physical layer of current optical networks. This Special Issue aims to consolidate and publish the latest research trends in order to fulfil the above goals. It will publish invited papers, original papers, short reviews, and proposals for future prospects.

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.
