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 $\hat{I}¸$-term as a benchmark. SKQD…
