Superconducting qubits based on Al Josephson junctions and coplanar waveguide resonators

Superconducting qubits are one of the most promising candidates for the physical implementation of quantum computing. In this paper, a brief review of superconducting qubits based on Josephson tunnel junctions and coplanar waveguide resonators is presented, focusing on Al/Al2O3/Al junctions, fabrication techniques, and important areas of opportunity for these devices. Simulation results of Al-based MIM capacitor structures and coplanar waveguide resonators are presented as an initial approach to the study of these devices and the impact of certain design parameters on their performance.
