Simulation and Characterization of Aluminium Three-Dimensional Resonator for Quantum Computation

We present the simulation and characterization of several aluminium three-dimensional (3D) resonators, which can be used for superconducting quantum computation. By changing the conductivity of the aluminium in a high frequency structure simulator, the loaded quality factor at room temperature and base temperature (20 mK) can be simulated. From S₂₁ measurement, we can characterize the properties of the resonators. The simulated and experimental results can be fitted well by exponential equations.
