Накратко на български

Връзката между структурата на пространството-времето и потока от квантова информация се анализира чрез синхронизиране на абстрактни координатни системи. Това помага за създаването на нови теоретични основи, които обединяват квантовата теория и общата теория на относителността.

Space-Time from Information Flow

The aim of this project was to begin developing a novel interdisciplinary approach to space-time physics, which not only combines core features of quantum theory and general relativity, but also takes the emerging information paradigm in physics serious. Informational perspectives and, in particular, the tools from quantum information have recently led to exciting progress in the quest for quantum gravity, both on the technical and conceptual level. Conversely, these developments give rise to new challenges and opportunities for quantum information research. This project aimed at furthering these developments through three main objectives: - The first objective was to better understand the relation between space-time structure and the feasibility of certain abstract quantum communication tasks. For example, how can spatiotemporal structure be inferred from operational conditions on abstract reference frame synchronisation protocols without putting it in a priori? - The second objective was to expand such a procedure of extracting spatiotemporal structure from observer communication relations to a semiclassical gravity regime. - The third objective was to deepen the perspective of viewing the architecture of space-time operationally as a network of quantum degrees of freedom exchanging information. The intention was to foster new information-theoretic foundations for space-time physics and to complement, rather than compete with, existing approaches to (quantum) gravity.

Цел на проекта

The aim of this proposal is to develop a novel multidisciplinary approach to space-time physics which combines core features of quantum theory and general relativity by using modern tools of information theory. Recent results manifest a deep relation between space-time structure and the possibility of certain abstract quantum communication tasks. We shall build upon these results to identify precise operational conditions on abstract quantum communication which permit observers to describe their environment as a classical space-time. This procedure will be expanded to spatiotemporal structures in a semiclassical regime with an emphasis on how the feasibility of communication tasks is influenced. Exploiting these insights, we shall devise a novel framework for (quantum) gravitational physics to generating spatiotemporal structure from the internal information flow of an operationally defined network. This research programme may foster new perspectives on space-time physics by providing it with information theoretic foundations and is intended to complement, rather than compete with, already existing approaches to (quantum) gravity.The fellowship will reintegrate the researcher from Canada into the EU and, at the same time, support the cross-community move of a (quantum) gravity expert into a quantum foundations group. The proposed programme requires expertise from various disciplines in theoretical physics and will thereby diversify the competences of both the researcher and the host group, as well as expand their respective networks of collaborators. This action supports European excellence in science and prepares the fellow for a more permanent position by endowing him with crucial opportunities to train his mentoring, communication and networking skills and, ultimately, by allowing him to develop his own research programme.
