Using quantum technologies and quantum information theory methods for studying lattice gauge theories

Abstract
While the road to a full scale universal quantum computer is still long, in the last decades an enormous progress has been made along it. In particular, new techniques for complex many-body quantum systems based on concepts from quantum technology and information are nowadays available, allowing one to study non-perturbative, strongly correlated physics, using current technologies.
In my talk I will focus on two such approaches - quantum simulation and tensor network states. The first suggests building non-universal quantum devices which mimic the dynamics of quantum man-body models, and the latter to use the power of entanglement to significantly simplify the study of quantum models on classical computers. In particular, I will demonstrate how these tools can be applied for studying lattice gauge theories, aiming (in the long term) at open questions in particle physics.
