Abstract
Quantum processing units (QPUs) based on configurable arrays of Rydberg atoms (CARA) represent a powerful emerging technology. Understanding the properties of CARA will enable us to better optimize this technology and apply it to a wider range of problems. Recently, two-leg Rydberg ladders have been proposed as simulators for scalar electrodynamics (sQED). For some aspect ratios of the ladder, the phase diagram remains not well understood. We employ two distinct methods to study the phases of two-leg Rydberg ladders, aiming to elucidate potential continuum limits. Our results demonstrate how the ground states evolve as a function of the number of rungs, aspect ratio, and Hamiltonian parameters. Additionally, we explore the properties and applications as the system size increases, utilizing a sequence of methods.

Quantum mechanics is one of the most successful scientific theories in history. However, progress in this field has gradually slowed, largely due to the inefficiency of classical computers in solving quantum problems. To address this challenge, researchers are investigating new types of computers that directly harness quantum mechanics. These quantum computers have shown promising developments and received significant funding in recent years. In this thesis, we study the behavior of quantum computers that rely on Rydberg atoms. These devices have been proposed as simulators for simple models in quantum field theory, making them highly relevant. We explore the properties of Rydberg atom devices to understand how they can be used to solve more complex quantum systems.
