Digitizing SU(2) Gauge Fields and What to Look Out for When Doing So
Tobias Hartung, Timo Jakobs, Karl Jansen +2
With the long term perspective of using quantum computers and tensor networks for lattice gauge theory simulations, an efficient method of digitizing gauge group elements is needed…
Exploring the phase structure of the multi-flavor Schwinger model with quantum computing
Lena Funcke, Tobias Hartung, Karl Jansen +4
We propose a variational quantum eigensolver suitable for exploring the phase structure of the multi-flavor Schwinger model in the presence of a chemical potential. The parametric…
Defining Canonical Momenta for Discretised SU(2) Gauge Fields
Marco Garofalo, Tobias Hartung, Karl Jansen +3
In this proceeding contribution we discuss how to define canonical momenta for SU(N) lattice gauge theories in the Hamiltonian formalism in a basis where the gauge field operators…
Track reconstruction at the LUXE experiment using quantum algorithms
Arianna Crippa, Lena Funcke, Tobias Hartung +8
LUXE (Laser Und XFEL Experiment) is a proposed experiment at DESY which will study Quantum Electrodynamics (QED) in the strong-field regime, where QED becomes non-perturbative. Mea…
Zeta-regularized Lattice Field Theory with Lorentzian background metrics
Tobias Hartung, Karl Jansen, Chiara Sarti
Lattice field theory is a very powerful tool to study Feynman's path integral non-perturbatively. However, it usually requires Euclidean background metrics to be well-defined. On t…
Classical Splitting of Parametrized Quantum Circuits
Cenk Tüysüz, Giuseppe Clemente, Arianna Crippa +3
Barren plateaus appear to be a major obstacle to using variational quantum algorithms to simulate large-scale quantum systems or replace traditional machine learning algorithms. Th…
