quantum gravity

This conference aims to bring together disparate communities in quantum gravity and quantum information to discuss common foundational concepts, which are defined and employed in different ways across fields. Central topics will include the notions of observers and causality, but the scope extends to related ideas such as measurements, quantum reference frames, quantum groups, and more.

We are happy to announce the 15th Annual Conference on Relativistic Quantum Information (North), which will take place on June 23–27, 2025, at the Università degli Studi Federico II, Napoli, Italy. This will be the main annual conference of the "International Society for Relativistic Quantum Information" (ISRQI), https://www.isrqi.net/, for the Northern hemisphere in 2025.

We encourage you to circulate the announcement among colleagues and students who may be interested in the event.

The XIII International Symposium on Quantum Theory and Symmetries (QTS-13), organized by the International Center for Advanced Studies and Physics Department of the Yerevan State University will be held in Yerevan, Armenia on 28 July - 1 August, 2025. The Symposium QTS-13 is dedicated to the memory of George Pogosyan. Professor Poghosyan was a distinguished theoretical physicist and a leading expert in the field of symmetry methods in physics. His research in mathematical physics has left a significant impact and is widely cited in the scientific community. As a co-founder of the International Center for Advanced Studies at Yerevan State University, along with Academician A. Sissakian, and as its director, he played a key role in fostering international collaborations and advancing fundamental physics. He also organized numerous international conferences, bringing together scientists from different countries to discuss modern developments in quantum theory and symmetries. The purpose of the Conference is to bring together scientists who knew Professor George Poghosyan personally and work with him, or who were influenced by his work.

In the first qmeets talk, Professor Silke Weinfurtner and Dr. Patrik Svancara from the University of Nottingham will introduce quantum simulations of curved spacetimes around rotating compact objects like black holes. They’ll reveal how quantum tornadoes—giant vortices in superfluid helium—can help decode signals captured by gravitational wave detectors, bringing us closer to understanding the cosmos.

Abstract:

The Conference focuses on causality and non-locality in physics, and the insurgence of situations where it appears that causality can be violated, with emphasis on their relation with time machines. There are three main objectives before this conference:

The search for a theory which would unite the insights of general relativity with those of quantum theory, a theory of quantum gravity, has now lasted the better part of a century. Although a number of promising candidate theories have emerged (string theory and loop quantum gravity being the most prominent), a large array of conceptual, formal and methodological issues are still unresolved.
