Demonstrating magnetic field robustness and reducing temporal T1 noise in transmon qubits through magnetic field engineering
Bektur Abdisatarov, Tanay Roy, Daniel Bafia +10
The coherence of superconducting transmon qubits is often disrupted by fluctuations in the energy relaxation time (T1), limiting their performance for quantum computing. While back…

Exploration of Parameters That Affect High Field Q-Slope
K. Howard, Y. -K. Kim, D. Bafia +1
The onset of high field Q-slope (HFQS) around 25 MV/m prevents cavities in electropolished (EP) condition from reaching high quality factors at high gradients due to the precipitat…

The Collaborative Effects of Intrinsic and Extrinsic Impurities in Low RRR SRF Cavities
K. Howard, Y. -K. Kim, D. Bafia +1
The superconducting radio-frequency (SRF) community has shown that introducing certain impurities into high-purity niobium can improve quality factors and accelerating gradients. W…
