Recent advances in fabricating superconducting circuits have allowed large numbers of microwave resonators and superconducting qubits to be employed in such circuits, but shared quantum entanglement among the photonics states of the resonators has not been attempted. Theorists now present a proposal that uses superconducting circuits to simulate a particular many-body quantum model that until now has been experimentally inaccessible and to create a type of shared quantum entanglement with the simulation.

This thesis deals with controlled interactions between superconducting circuit elements for quantum computation and simulation applications. First, the electrical design and measurements of transmon type qubits, which are coupled to superconducting resonators, are presented. Secondly the controllable coupling of superconducting microwave resonators via an rf SQUID is experimentally investigated. Thirdly, a theoretical discussion about interaction and entanglement of a microwave resonator with a nanomechanical beam via an rf SQUID is discussed.

Multimode microwave resonators that can be strongly coupled to superconducting qubits allow exploration of large-scale entanglement, or quantum simulations of many-body phenomena. Typically, long superconducting transmission lines or large arrays of transmission-line resonators are required. This work demonstrates superconducting metamaterial resonators with a dense mode spectrum above a low-frequency band gap. Imaging of the microwave fields shows that these devices exhibit a left-handed dispersion relation, consistent with modeling and simulations. This compact design is compatible with superconducting-qubit integration for applications in quantum information and communication.
