Special Issue Information
Dear Colleagues,
Long distance quantum communications are of fundamental importance today, due to their applications to secure communication, such as quantum key distribution, quantum authentication and quantum digital signature, as well as to fundamental physics, like long distance entanglement distribution, quantum teleportation, and the study of gravitational effects on quantum states. Besides these applications, quantum communications are a fundamental prerequisite for the realization of quantum networks, toward a future quantum internet. While quantum communications have been the object of a widespread interest by the scientific community, the reach of ground-based demonstrators is limited so far to a few hundred kilometers, due to the unavoidable attenuation of light during the propagation in optical fibers. For this reason, for more than two decades, satellite communication links have been studied in hopes of solving this problem, both theoretically and with proof of principle demonstrators. The outstanding results obtained by the Chinese Quantum Science Satellite (QSS) have shown how the field is now ready to move to the next step, opening the era of satellite quantum communication. These results have attracted the interest of the scientific community, governments, and stakeholders, and several other missions are foreseen in the next future, aiming at expanding even further the results obtained so far.
The MDPI journal Sensors has decided to address this flourishing research topic by launching a Special Issue dedicated to satellite quantum communication. This issue will gather both theoretical and experimental contributions in this emerging field. Topics of interest include (but are not limited to):
- Satellite quantum terminals
- New mission proposals
- Applications of satellite quantum communication
- Investigation of gravitational effects on quantum communication
- Link budget estimation
- Atmospheric effect mitigation
- Quantum internet and the role of satellite links

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. Sensors 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 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.

Benefits of Publishing in a Special Issue
- Ease of navigation: Grouping papers by topic helps scholars navigate broad scope journals more efficiently.
- Greater discoverability: Special Issues support the reach and impact of scientific research. Articles in Special Issues are more discoverable and cited more frequently.
- Expansion of research network: Special Issues facilitate connections among authors, fostering scientific collaborations.
- External promotion: Articles in Special Issues are often promoted through the journal's social media, increasing their visibility.
- e-Book format: Special Issues with more than 10 articles can be published as dedicated e-books, ensuring wide and rapid dissemination.
