Special Issue Information
Dear Colleagues,
As a crucial component of the quantum internet, quantum key distribution (QKD) offers potential advantages for securing information exchanged between two remote parties. Unlike current classical cryptography, which relies on computational complexity, QKD provides unconditional security grounded in the fundamental principles of quantum mechanics. Since the development of the first QKD protocols, such as BB84 based on single-photon states and E91 based on quantum entanglement states, both theoretical and experimental progress in QKD has been rapid. Recently, QKD systems achieving key rates exceeding 100 Mbps and distances over 1000 km have been demonstrated in laboratory and field settings, particularly leveraging satellites and drones, paving the way for long-distance secure quantum internet. However, several important challenges must be addressed to enable the widespread practical application of QKD.
The first challenge involves increasing the final key rate for a given distance and extending the maximum distance without relying on quantum repeaters. The second challenge is to mitigate practical security vulnerabilities introduced by potential imperfections in QKD devices. The third challenge entails integrating QKD with classical cryptography systems to facilitate its acceptance and use by customers.
This Special Issue aims to focus on the recent developments in QKD. We welcome all papers related to secure communication based on quantum principles, not only those concerning QKD but also post-quantum cryptography (PQC).

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.
