Microwave Characterization of Josephson Junction Arrays: Implementing a Low Loss Superinductance
We have measured the plasma resonances of an array of Josephson junctions in the regime ${E}_{J}\ensuremath{\gg}{E}_{C}$, up to the ninth harmonic by incorporating it as part of a resonator capacitively coupled to a coplanar waveguide. From the characteristics of the resonances, we infer the successful implementation of a superinductance, an …
