Dear Colleagues,
Both in the field of quantum gravity and in quantum information theory, the importance of topology is increasing. The discovery of topological phases of matter, together with the existence of analogue systems of gravity and their evident relation to quantum information, bring interesting scenarios where important discoveries will appear.
As first proposed by Andrei Sakharov in 1967, gravity as we experience it in real life might emerge as a mean field approximation of underlying microscopic degrees of freedom of a quantum field theory. It is also possible that some unexplained aspects of gravity might emerge as a collective effect originally from microscopic degrees of freedom.
The most evident connection between gravity and quantum information can be visualized through the physics of black holes where the area of the event horizon measures the amount of information hidden behind it. The Hawking radiation and its associated thermality bring as a consequence the existence of the famous black hole information paradox discovered by Hawking in his seminal papers on the subject.
In addition, the proved connections between the physics of black holes and some condensed matter systems bring scenarios where quantum information can be analyzed from the perspective of condensed matter systems and subsequently mapped to gravitational systems for a deeper understanding of gravity.
Furthermore, deep relations between entanglement and the Einstein field equation have been explored by many authors, such as the ER=EPR correspondence proposed by Suskind and Maldacena in relation to the AdS/CFT duality.
In this sense, understanding topological aspects in gravity might have a direct relation to topological aspects in related field theories as well as in condensed matter systems. These important subjects will be explored in this Special Issue.
This Special Issue invites contributions reporting progress related to topological aspects both in the field of quantum gravity and in quantum information theory. Moreover, contributions focusing on suitable pedagogical introductions and model building related to existing theories are welcome.

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. Symmetry 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.
