Failure of Conventional Roughness Metrics in Assessing Field-Limiting Mesoscopic Topography in SRF Nb Films on Cu
Eric M. Lechner, Brandi Redman, Theodore S. Cahall +1
A characteristic corrugated surface morphology of Nb films on Cu is identified, with mesoscopic features comparable to the London penetration depth and coherence length, and its im…
Design optimization, commissioning, and uncertainty analysis of the quadrupole resonator system at Jefferson Lab for SRF material characterization
Mingqi Ge, Sarra Bira, Kristof Brunner +14
A quadrupole resonator (QPR) provides a sample-based platform for characterizing materials for superconducting radio-frequency (SRF) applications under controlled field, frequency,…
RF-Budgeted Frame Compilation for Frequency-Multiplexed Superconducting-Qubit Control Using Qubit-Control Identity Records and a Circuit-Informed RFSoC Model
Mingqi Ge, Anne-Marie Valente-Feliciano
Frequency-multiplexed superconducting-qubit control requires more than carrier assignment: the RF budget of a shared source can perturb multi-qubit rotations through finite bandwid…
Investigation of coherence of niobium-based resonators enabled by a fast-sealing microwave cavity
Chi Zhang, Richard Germond, Noah Janzen +3
Resonators and qubits with a niobium (Nb) base metal layer achieve some of the highest coherence times in superconducting quantum devices. The performance of such devices is often…
Microscopic parameters of a type-II superconductor measured by small-angle neutron scattering
D. Alba Venero, A. -M. Valente-Feliciano, O. O. Bernal +1
A necessary condition for understanding and predicting the properties of any material is knowledge of microscopic parameters which control these properties in a state of thermodyna…
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…
