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…
Digitising SU(2) Gauge Fields and the Freezing Transition
Tobias Hartung, Timo Jakobs, Karl Jansen +2
Efficient discretisations of gauge groups are crucial with the long term perspective of using tensor networks or quantum computers for lattice gauge theory simulations. For any Lie…
Lattice meets lattice: Application of lattice cubature to models in lattice gauge theory
Tobias Hartung, Karl Jansen, Frances Y. Kuo +3
High dimensional integrals are abundant in many fields of research including quantum physics. The aim of this paper is to develop efficient recursive strategies to tackle a class o…
Dimensional Expressivity Analysis of Parametric Quantum Circuits
Lena Funcke, Tobias Hartung, Karl Jansen +2
Parametric quantum circuits play a crucial role in the performance of many variational quantum algorithms. To successfully implement such algorithms, one must design efficient quan…
