Materials Engineering in Superconducting Qubits

ORAL

Abstract

During the early days of superconducting qubits, increases in coherence times were frequently driven by improvements in materials and fabrication techniques. More recent advances have focused on manipulating capacitive, inductive, and Josephson energy scales, as well as engineering favorable qubit environments. In this talk we again focus on materials engineering of qubits. We explore how new materials and surface treatments can improve coherence times. Furthermore, we correlate the results of materials spectroscopy and time domain measurements to provide insight into relaxation mechanisms.
