Resonators for hybrid superconductor-atom spin systems

Coplanar microwave resonators made of superconducting thin films represent a central building block of quantum electrodynamics with integrated circuits, in which the fundamental interaction of microwave-photons with artificial atoms of superconducting modules is studied. Because of the good control, the selective making for, and the scalability of superconducting quantum bits, short qubits, these strongly coupled systems, consisting of superconducting microwave resonators and superconducting qubits, are promising candidates for the realization of a quantum technology, which is suited to process quantum information under usage of highly efficient algorithms and by this surpass their classical counterparts. Because of the short coherence times of superconducting qubits of about 100 μs however the calculation time of such a quantum computer is limited. In order to overcome these limitations, a multitude of hybrid quantum systems was proposed, which combine the advances of different quantum systems. The present thesis deals with different aspects for the
