Identification and Mitigation of Conducting Package Losses for Quantum Superconducting Devices
Yizhou Huang, Yi-Hsiang Huang, Haozhi Wang +4
Low-loss superconducting rf devices are required when used for quantum computation. Here, we present a series of measurements and simulations showing that conducting losses in the…
Characterization of Asymmetric Gap-Engineered Josephson Junctions and 3D Transmon Qubits
Zach Steffen, S. K. Dutta, Haozhi Wang +6
We have fabricated and characterized asymmetric gap-engineered junctions and transmon devices. To create Josephson junctions with asymmetric gaps, Ti was used to proximitize and lo…
Long-lived transmons with different electrode layouts
Kungang Li, S. K. Dutta, Zachary Steffen +6
To test the contribution of non-equilibrium quasiparticles to qubit relaxation, we have repeatedly measured the relaxation time T_1 in Al/AlOx/Al transmons with electrodes that hav…
