Novel Approaches for Optimizing Materials in Superconducting Quantum Systems

I am an ECE graduate student working in the group of Chris Palmstrøm. My research focusses on the development of high-quality superconducting material systems with applications in quantum information systems. During this talk, I will highlight two unique approaches taken in our lab to potentially decrease losses in these type of material systems. The first part will discuss the effect of cryogenic growth (Tsubstrate < 10 K) of Tantalum and the importance of substrate preparation and analysis in ultra high vacuum. The second part of the talk will focus on our efforts to create single crystalline tunnel barriers
that can be used as Josephson junctions and potentially in superconducting qubits.
