Tunneling Spectroscopy Study of Low Baked Bulk Niobium for Superconducting RF Cavity Applications
Ivana Curci, Gregoire Jullien, Luc Maurice +3
Point-contact tunneling (PCT) spectroscopy was used to probe the local superconducting properties of cavity-grade niobium following surface treatments representative of superconduc…
Microwave characterization of superconducting coplanar resonators made out of granular aluminium
Kelvin J. Ramos, Ivana Curci, Erick Potosí +4
We have designed, fabricated and characterized microwave resonators made out of thin films of granular aluminium (grAl) with different oxygen content. We extract the contribution o…
Superconducting properties of thin film studied via the NMR of implanted Li
Md Asaduzzaman, Ryan M. L. McFadden, Edward Thoeng +10
We report measurements of the normal-state and superconducting properties of thin-film using Li -detected nuclear magnetic resonance (-NMR). In…
Crystallinity in Niobium oxides: A pathway to mitigate Two-Level System Defects in Niobium 3D Resonator for quantum applications
Y. Kalboussi, I. Curci, F. Miserque +10
Materials imperfections in Nniobium based superconducting quantum circuits, in particular, two-level-system (TLS) defects, are a major source of decoherence, ultimately limiting th…
