Quantum Information in Quantum Gravity Group

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.

About Our Group

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.
