Quantum Entanglement and Holographic Universe

Dear Colleagues,

Quantum entanglement plays an essential role in the modern understanding of gravity. The Ryu–Takayanagi formula reveals a deep relation between spacetime geometry and quantum entanglement. Remarkably, the Einstein equations in bulk can be obtained from the first law of entanglement entropy of conformal field theories on the boundary. Furthermore, studying quantum entanglement in holographic gravity leads to a significant breakthrough toward resolving the black hole information paradox, for which many novel physical concepts, such as the quantum extremal surface and island, are developed. What new information can quantum entanglement tell us about the universe? Could it shed light on the black hole singularity or the universe's accelerating expansion? Many important questions remain to be explored.

This Special Issue invites articles on a wide range of topics on quantum entanglement, the AdS/CFT correspondence, and the holographic universe. The aim is to inspire new ideas and apply the methods of quantum information to investigate the central problems of gravity and the universe.

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. Universe is an international peer-reviewed open access monthly journal published by MDPI.

Please visit the Instructions for Authors page before submitting a manuscript. 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.
