Entanglement in Quantum Field Theory and Its Applications

Dear Colleagues:

Quantum field theory is the most successful scientific theory with incredible experimental evidence. It works as a universal language for the standard model of elementary particles and condensed matter systems. The study of entanglement in the context of quantum field theory has gained considerable interest over the last several decades due to the fact that the vacuum state of a free quantum field is entangled and contains information about the structure of space-time through the boundary conditions. In turn, the vacuum fluctuations induce entanglement generation in atomic probes and condensed matter systems such as 2D materials.

Entanglement is a fundamental feature of quantum theory as well as a key resource for quantum computing and quantum communication. It is important, therefore, for fundamental research as well as for practical applications, to study the mechanisms by which entanglement can be generated and transferred.

This Special Issue aims to be a forum for a discussion of entanglement in quantum field theory with emphasis on recent developments such as, but not limited to, those described above.

Contributions on the following topics are particularly welcome: entanglement in quantum field theory, information holography, quantum teleportation, quantum cryptography, entanglement harvesting, topological quantum field theory and correlated electrons in condensed matter.

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. Axioms 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.
