Special Issue Information
Dear Colleagues,
Over the last millennium, quantum optics has made huge progress in both science and engineering fields. In science, quantum nonlinear optics in atomic and optical physics has been driven towards new phenomena such as electromagnetically induced transparency, ultraslow light, stop light, photon echoes, and quantum memories via atom–field interactions. In engineering fields, various quantum technologies have also been developed, where quantum information has drawn particular attraction in quantum computing, quantum communications, and quantum metrology. Based on the complementarity theory, quantum information has mostly dealt with the particle nature of quantum mechanics. The fundamental aspect of the particle nature is in the two-photon correlation such as anticorrelation, the so-called Hong–Ou–Mandel effect, and Bell inequality violation. In experiments, nonclassical light from nonlinear optical processes such as spontaneous parametric down conversion and squeezed light have been mostly used as quantum light sources. Nondeterminacy has been a central concept in quantum information. In this Special Issue, we focus on both the fundamental physics of quantum optics which has progressed over the last hundred years. For this, both review and research papers are invited from the quantum optics community. The following subjects are open to the Special Issue: General quantum mechanics, EPR/Bell inequality violation, two-photon correlation, quantum interface, quantum memory, quantum logic gate, quantum key distribution, quantum computing, quantum systems, quantum sensing and metrology, and emerging quantum optics.

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.

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.
