Special Issue Information
Dear Colleagues,
In recent years, optical quantum technologies have taken a firm step into the spotlight, ushering in breakthroughs across quantum communication, computation, sensing, and networking. While long-standing goals, such as large-scale error-corrected quantum computers, remain aspirational, the community now recognizes the immense potential and practicality of noisy intermediate-scale quantum (NISQ) systems, especially when harnessed via optical platforms. In this Special Issue, we explore significant strides in light-source engineering, photonic integration, and nonlinear and linear optics, driving practical applications across:
- Quantum communication: advances in key distribution, entanglement swapping, quantum repeaters, and high‑dimensional encoding in fiber, free‑space, and underwater channels;
- Quantum networks: milestones such as photonic inter-module entanglement and distributed quantum algorithms;
- Quantum computing and simulation: cutting-edge work in integrated quantum photonics, including chip-based gates and path-/polarization-encoded logic;
- Photonic devices: innovations in photon sources (single‑ and entangled‑photon emitters), high‑efficiency detectors (SNSPDs/SPADs), modulators, converters, and memories;
- Quantum sensing/imaging: exploitation of squeezed light, entanglement, and quantum coherence to improve measurement accuracy, resolution, and sensitivity.

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.
