Characterizing Granular Aluminum in Superconducting Circuits*

High kinetic inductance materials are promising candidates for implementing large inductances which are crucial for several proposed qubit designs. These materials also allow for a distributed nonlinear element, opening the door for a new family of qubits. Here, we present a new method to deposit granular aluminum in addition to spectroscopic and time domain measurements of granular aluminum-based superconducting qubits.
