Special Issue Information
Dear Colleagues,
Single-photon sources are in a great need for many applications in quantum physics. As a non-classical light source, single-photon sources are used to demonstrate the principle of quantum mechanics, illustrating quantum strangeness, such as the wave–particle duality of light. On the other hand, techniques of quantum information based on the principle of quantum mechanics need single-photon sources to realize quantum cryptography and quantum computation. Especially, in quantum cryptography it encodes the secret key information on a sequence of single photons. Any measurement will unavoidably modify the eigenstate of the single quantum system, hence an eavesdropper cannot gather information about the secret key without being revealed, provided that the pulses used in transmission do not contain two or more photons.
Up to now, many single-photon sources have been developed, including single atoms and ions in a trap, single molecules, single quantum dots, and single optically active defects in solids. New applications of single-photon sources also emerge. Therefore, this Special Issue aims to provide the newest developments in the rapidly evolving research fields of single-photon generation. We welcome papers that highlight recent breakthroughs and improvements in single-photon generation and related applications.
Topics covered include, but are not limited to:
- Single-photon sources and related applications;
- Entangled-photon pair sources;
- Single-photon frequency conversions;
- Calibration of single-photon detection with single-photon sources;
- Photon-number resolving detection;
- Cavity-enhanced single-photon generation.

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. Photonics 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 2400 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.
