Project funded by Research Council of Finland, grant 341985. Participating organisations named by the source: University of Helsinki. Funded amount: EUR 103,235, as stated by the source. Runs 2021-09-01 to 2022-10-24. Keywords: Physical sciences. Source: OpenAIRE Graph, from the funder's project data (collected by OpenAIRE on 2026-07-23); national funding data, not CORDIS. Abstract given by the source: Entanglement lies at the very heart of quantum theory, both as one of the fundamental features that distinguish it from classical reality and as a crucial resource for quantum technologies. Remarkably, it has been discovered that entanglement in paradigmatic many-body quantum systems can present geometric properties. The main objective of this highly interdisciplinary project is to deepen our understanding of these emergent entanglement-geometric structures by using the tools of network geometry, a field of complex network theory that has identified hyperbolic geometry underlying complex systems as disparate as the human brain and the Internet. This approach has the potential to produce intuitive network models characterising complex entanglement structures, to provide new tools for theories that consider gravity as an emergent quantum phenomenon, and to design new efficient techniques exploiting quantum advantage for simulations on near-term quantum computers.
