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.
New position: Interested in joining our group? We have a new postdoc position for 12 months here. Apply before 05.03.2023!
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.

Our group is a part of the Institute of Theoretical Physics, Chair of Quantum Mathematical Physics, Faculty of Physics of the University of Warsaw, Poland. It currently contains four 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: NAWA Polish Returns 2019 Holographic Geometry and Quantum Information and NCN Sonata Bis 9 Quantum Information in Quantum Field Theories and Holography: Dynamics and Complexity.
