Quantum simulation strategies for lattice gauge theories

About

This reseach field focuses on the development of quantum simulation strategies for lattice gauge theories, with particular emphasis on compact Maxwell–Chern–Simons theories and non-perturbative phenomena such as confinement, topological order, and ground-state degeneracy. These studies are motivated by the prospect of using quantum computers and tensor-network methods to investigate strongly correlated quantum systems beyond the reach of classical simulations.

Earlier contributions include the development of quantum associative memory models, where quantum superposition and interference are exploited for information storage and retrieval. More recently, the implementation of topological gauge theories and superinsulating phases on quantum computing platforms have been explored, with the goal of identifying robust quantum states protected by topological mechanisms.

Collaborators include Carlo A. Trugenberger, Karl Jansen, Enrique Rico, Tobias Hartung, Lena Funcke and other members of international collaborations working at the interface of quantum information, lattice gauge theory and condensed matter physics.
