In this thesis we describe experiments which explore 1D transport at the LaAlO3/SrTiO3 interface. Complex oxide systems, specifically those based on SrTiO3, possess a wide range of magnetic and electronic properties, including superconductivity, magnetism, ferroelectricity, and ferroelasticity. Electron waveguide devices created at the LaAlO3/SrTiO3 interface exhibit quantized ballistic transport of electrons, electron pairs, and Pascal liquid phases-bound states of more than two electrons. Different types of periodic modulation are applied to the electron waveguides to create one-dimensional superlattices. By creating superlattice devices we are able to engineer new properties and enhance electron-electron interactions at the LaAlO3/SrTiO3 interface. These devices represent a first step towards developing a solid-state quantum simulation platform and will be used as building blocks for creating more complex quantum systems.
