Our main goal is to explore quantum gravity using quantum information.
Our current focus is on developing quantum information tools, such as measures of entanglement or complexity, in quantum field theories and using them to understand the relation between holographic geometry and quantum entanglement.

Focus week on dynamics of QI. This week our visitors Diptarka Das (IIT Kanpur) and Felix Haehl (U. of Southampton) will give seminars on: „Virasoro blocks and quasimodular forms” (DD) and „Effective theory of sub-maximal chaos” (FH) as well as series of pedagogical lectures on: „Quantum quenches and restoration of symmetry” (DD) and „Schwinger-Keldysh formalism”, „Hydrodynamics” and „Open systems in holography” (FH). More details also here.

New result: „BPS and near-BPS black holes in AdS5 and their spectrum in N=4 SYM.” by Jan Boruch (UW), Matthew T. Heydeman (Princeton U.), Luca V. Iliesiu (Stanford U.) and Gustavo J. Turiaci (Princeton U.)
New result: „A new measure of quantum state complexity.” by Vijay Balasubramanian (U. Penn), Pawel Caputa (UW), Javier Magan (U. Penn), Qingyue Wu (U. Penn).
Our group is a part of the Faculty of Physics of Stockholm University and The Oscar Klein Centre, Stockholm, Sweden. It currently contains five members (meet our team).
Our research lies at the intersection of quantum information, quantum field theory, holography and quantum gravity. At the moment we carry out two projects: ERC Consolidator Grant (Stockholm) „Quantum Complexity from Quantum Field Theories to Quantum Gravity (QComplexity)” and NCN Sonata Bis 9 (Warsaw) „Quantum Information in Quantum Field Theories and Holography: Dynamics and Complexity”.
