Charge Parity Rates in Transmon Qubits with Different Shunting Capacitors
Yi-Hsiang Huang, Haozhi Wang, Yizhou Huang +3
The presence of non-equilibrium quasiparticles in superconducting resonators and qubits operating at millikelvin temperature has been known for decades. One metric for the number o…
Fabrication of Metal Air Bridges for Superconducting Circuits using Two-photon Lithography
Yi-Hsiang Huang, Haozhi Wang, Zhuo Shen +3
Extraneous high frequency chip modes parasitic to superconducting quantum circuits can result in decoherence when these modes are excited. To suppress these modes, superconducting…
Generalized geometric speed limits for quantum observables
Jacob Bringewatt, Zach Steffen, Martin A. Ritter +6
Leveraging quantum information geometry, we derive generalized quantum speed limits on the rate of change of the expectation values of observables. These bounds subsume and, for Hi…
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…
Perspective: Reproducible Coherence Characterization of Superconducting Quantum Devices
Corey Rae H McRae, Gregory M Stiehl, Haozhi Wang +5
As the field of superconducting quantum computing approaches maturity, optimization of single-device performance is proving to be a promising avenue towards large-scale quantum com…
Overlap junctions for superconducting quantum electronics and amplifiers
Mustafa Bal, Junling Long, Ruichen Zhao +10
Due to their unique properties as lossless, nonlinear circuit elements, Josephson junctions lie at the heart of superconducting quantum information processing. Previously, we demon…
