Superconducting qubits are at the heart of many experiments exploring elementary quantum mechanics and are one of the principal candidates for use in a future quantum computer. In both cases, a high level of control over both the quantum system and its environment is necessary. The first chapters of this thesis describe several techniques used to engineer the effect of the environment in circuit QED with a focus on the promising Fluxonium qubit. We give a detailed treatment of the theoretical basis for protected qubits and analyse device design and dilution refrigerator wiring from the perspective of environment noise reduction. As an application of these methods, we reproduce state of the art conditions for Fluxonium experiments in order t...
