Novel Computing Approaches with Superconducting Circuits*

Recently, considerable scientific interest has been generated by experimental approaches that employ superconducting circuits to the implementation of quantum information protocols. First, we review the different possibilities, with emphasis on Digital Quantum Simulations. We also discuss the premise that the entire physical universe is describable by information. Mainly, we present the results of our attempts to build a few highly controllable quantum systems to carry out some targeted quantum systems, including the Ising Spin Model, the Heisenberg Spin Model, and the Fermi-Hubbard Model. We also consider the use of parametric flux or voltage modulation.
