Lattice QIS: Euclidean Methods for Minkowski Calculations

ORAL

Abstract

The possibility for near-term quantum simulations in lattice field theory depends upon efficiently using the limited resources available. For the forseeable future, connecting toN large-scale classical simulations in Euclidean lattice field theory may prove invaluable. In this talk, we will discuss how approximating lattice gauge theories like SU(3) with discrete subgroups can be theoretically analyzed as a lattice effective field theory, and how the critical step of scale setting on quantum computers may be aided by Euclidean calculations. Methods for implementation upon quantum hardware will be covered. Numerical results for Euclidean and Minkowski calculation will be presented with modified and improved actions that relate to Hamiltonians other than Kogut and Susskind.
