(2+1)D quantum electrodynamics at finite density on a quantum computer

Emil Otis Rosanowski, Arianna Crippa, Lena Funcke +3

In this paper, we explore (2+1)D quantum electrodynamics (QED) at finite density on a quantum computer, including two fermion flavors. Our method employs an efficient gauge-invaria…

A Finite-Volume Scheme for the Continuum Extrapolation of Lattice Step-Scaling in (2+1)D Hamiltonian U(1) Gauge Theory

Alessio Negro, Emil Otis Rosanowski, Lena Funcke +4

We propose a finite-volume scheme to perform controlled continuum extrapolations of the lattice step-scaling function, a key ingredient for determining the running coupling in a Ha…

Sample-Based Krylov Quantum Diagonalization for the Schwinger Model on Trapped-Ion and Superconducting Quantum Processors

Emil Otis Rosanowski, Jurek Eisinger, Lena Funcke +2

We apply the recently proposed Sample-based Krylov Quantum Diagonalization (SKQD) method to lattice gauge theories, using the Schwinger model with a -term as a benchmark. SKQD…
