Thermodynamic-limit dispersion relations on trapped-ion quantum hardware
Lucas Marti, Sumeet, Stefan Wolf +2
We run a numerical linked-cluster expansion with a quantum algorithm (NLCE+QA), computing ground-state energies and one quasi-particle dispersions in the thermodynamic limit using…

Shot-noise reduction for lattice Hamiltonians
Timo Eckstein, Refik Mansuroglu, Stefan Wolf +4
Efficiently estimating energy expectation values of quantum lattice systems on quantum computers is a crucial subroutine for various quantum algorithms, which can lead to significa…

Variational Time Evolution Compression for Solving Impurity Models on Quantum Hardware
Stefan Wolf, Martin Eckstein, Michael J. Hartmann
Dynamical mean-field theory (DMFT) is a useful tool to analyze models of strongly correlated fermions like the Hubbard model. In DMFT, the lattice of the model is replaced by a sin…
