Quantum Photonics: Information Processing and Quantum Corrections

Dear Colleagues,

Among the new industries originating during the second half of the last century, photonics is now a multi-billion dollar market that has significantly changed our society. From large data-server farms to the screens of mobile devices we are surrounded by technologies which produce, manipulate, and convert light signals.

We are now experiencing the inception of a new generation of photonics devices, capable of producing and controlling quantum light. Quantum photonics will enable better sensing, imaging, metrology, data communication, and processing. In combination with biotechnology and renewable energy, quantum photonics will emerge as one of the key industries of the 21st century.

As an infant technology, there are still significant conceptual and technical challenges to overcome towards practical and scalable quantum photonics. At the base level, the on-demand generation of quantum states of light imposes a limitation on size and complexity. The losses imposed by silicon-based photonic fabrication is another key problem in this field. Finally, there is a large avenue for developing new and improved protocols for the fault-tolerant operation of quantum devices, making it possible to reduce overhead resources.

This Special Issue of Photonics, entitled Quantum Photonics Information Processing and Error Corrections, will focus on the challenges in achieving scalable quantum photonic technologies. This endeavor is a multi-disciplinary effort, encompassing fundamental and applied sciences. We expect to cover a variety of topics, including the generation of quantum states of light and applications, quantum sensing and imaging, integrated quantum photonics for quantum information processing, hybrid interfaces with quantum photonics, and quantum error correction.

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.
