Leakage benchmarking with decohering subgroups in the presence of preparation and measurement errors
Shawn Geller, Tongyu Zhao, Alex Kwiatkowski +3
A common problem with physical qubits is that the state can leak outside the computational subspace. To characterize the problem, it is desirable to measure both the leakage probab…
Interface-sensitive microwave loss in superconducting tantalum films sputtered on c-plane sapphire
Anthony P. McFadden, Jinsu Oh, Lin Zhou +5
Quantum coherence in superconducting circuits has increased steadily over the last decades as a result of a growing understanding of the various loss mechanisms. Recently, tantalum…
Fabrication and characterization of low-loss Al/Si/Al parallel plate capacitors for superconducting quantum information applications
Anthony McFadden, Aranya Goswami, Tongyu Zhao +7
Increasing the density of superconducting circuits requires compact components, however, superconductor-based capacitors typically perform worse as dimensions are reduced due to lo…
Towards merged-element transmons using silicon fins: the FinMET
Aranya Goswami, Anthony P. McFadden, Tongyu Zhao +7
A merged-element transmon (MET) device, based on silicon (Si) fins, is proposed and the first steps to form such a "FinMET" are demonstrated. This new application of fin technology…
