Impact of metallographic polishing on the RF properties of Niobium for SRF applications
Oleksandr Hryhorenko, Anne-Marie Valente-Feliciano, David Longuevergne +6
The performance of superconducting radio-frequency (SRF) cavities made of Niobium is tied to the quality of their inner surfaces exposed to the radio frequency (RF) waves. Future s…

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…
