Tunable Capacitor For Superconducting Qubits Using an InAs/InGaAs Heterostructure
Nicholas Materise, Matthieu C. Dartiailh, William M. Strickland +2
Adoption of fast, parametric coupling elements has improved the performance of superconducting qubits, enabling recent demonstrations of quantum advantage in randomized sampling pr…
Evolution of -periodic Supercurrent in the Presence of In-plane Magnetic Field
Bassel Heiba Elfeky, Joseph J. Cuozzo, Neda Lotfizadeh +5
In the presence of a 4-periodic contribution to the current phase relation, for example in topological Josephson junctions, odd Shapiro steps are expected to be missing. While m…
Superconducting resonators with voltage-controlled frequency and nonlinearity
William M. Strickland, Bassel Heiba Elfeky, Joseph O'Connell Yuan +6
Voltage-tunable superconductor-semiconductor devices offer a unique platform to realize dynamic tunability in superconducting quantum circuits. By galvanically connecting a gated I…
Magneto-anisotropic weak antilocalization in near-surface quantum wells
S. M. Farzaneh, Mehdi Hatefipour, William F. Schiela +6
We investigate the effects of an in-plane magnetic field on the weak antilocalization signature of near-surface quantum wells lacking bulk and inversion symmetry. The measured magn…
Controlling Fermi level pinning in near-surface InAs quantum wells
William M. Strickland, Mehdi Hatefipour, Dylan Langone +2
Hybrid superconductor-semiconductor heterostructures are a promising platform for quantum devices based on mesoscopic and topological superconductivity. In these structures, a semi…
Gate-tunable, superconductor-semiconductor parametric amplifier
D. Phan, P. Falthansl-Scheinecker, U. Mishra +4
We have built a parametric amplifier with a Josephson field effect transistor (JoFET) as the active element. The device's resonant frequency is field-effect tunable over a range of…
