Entanglement of quantum fields detected through entropic uncertainty relations (A06*)

• Subject Area: Nuclear and Elementary Particle Physics, Quantum Mechanics, Relativity, Fields
• Term: from 2020 to 2024
• Project identifier: Deutsche Forschungsgemeinschaft (DFG) - Project number 273811115

The central goal of this project is to employ concepts from quantum information theory to improve our understanding of non-equilibrium dynamics of in continuous quantum systems described by quantum fields. Entropic uncertainty relations are a promising starting point as they allow to derive an experimentally accessible lower bound on entanglement entropy which plays a crucial role for the thermalization of closed quantum systems. We will experimentally measure entanglement bounds based on entropic uncertainty relations and develop the field theoretical formalism for their quantum field theoretic description.
