| Publication Abstract: | Quantum computing may offer the opportunity to simulate strongly-interacting field theories, such as quantum chromodynamics, with physical time evolution, in contrast to the Euclidean- signature calculations routinely performed at present. However, all simulation strategies considered to date still require defining the theory in a finite periodic volume. In this work, we investigate the consequences of this modification for both purely hadronic and Compton-like amplitudes. Using the framework presented Phys. Rev. D101 014509 (2020), we quantify the effects for various 1+1D systems and show that these can be a significant source of systematic uncertainty, even for volumes that are very large by the standards of modern Euclidean calculations. We further show that a combination of different momenta in the finite-volume frame, together with binning over various kinematic variables, can suppress the unwanted volume distortions and improve the extraction of scattering amplitudes. |
