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…
Implementing two-qubit gates at the quantum speed limit
Joel Howard, Alexander Lidiak, Casey Jameson +8
The speed of elementary quantum gates, particularly two-qubit gates, ultimately sets the limit on the speed at which quantum circuits can operate. In this work, we experimentally d…
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…
Cryogenic microwave loss in epitaxial Al/GaAs/Al trilayers for superconducting circuits
C. R. H. McRae, A. McFadden, R. Zhao +7
Epitaxially-grown superconductor/dielectric/superconductor trilayers have the potential to form high-performance superconducting quantum devices and may even allow scalable superco…
