Machine learning analysis of structural data to predict electronic properties in near-surface InAs quantum wells
Patrick J. Strohbeen, Abtin Abbaspour, Amara Keita +12
Semiconductor crosshatch patterns in thin film heterostructures form as a result of strain relaxation processes and dislocation pile-ups during growth of lattice mismatched materia…
Microwave radiometry of a quantum-critical, hybrid Josephson array
Kristen W. Léonard, Anton V. Bubis, Melissa Mikalsen +6
Arrays of Josephson junctions can be tuned through anomalous metallic, quantum-critical, and insulating regimes. We introduce a new experimental probe, capturing microwave radiatio…
Microwave Andreev bound state spectroscopy in a semiconductor-based Planar Josephson junction
Bassel Heiba Elfeky, Krishna Dindial, David S. Brandão +13
By coupling a semiconductor-based planar Josephson junction to a superconducting resonator, we investigate the Andreev bound states in the junction using dispersive readout techniq…
Gatemonium: A Voltage-Tunable Fluxonium
William M. Strickland, Bassel Heiba Elfeky, Lukas Baker +6
We present a new style of fluxonium qubit, gatemonium, based on an all superconductorsemiconductor hybrid platform. The linear inductance is achieved using six hundred planar Al-In…
Gate tunable enhancement of supercurrent in hybrid planar Josephson junctions
Peng Yu, Han Fu, William F. Schiela +6
Planar Josephson junctions (JJs) have emerged as a promising platform for the realization of topological superconductivity and Majorana zero modes. To obtain robust quasi one-dimen…
Kerr nonlinearity and parametric amplification with an Al-InAs superconductor-semiconductor Josephson junction
Z. Hao, T. Shaw, M. Hatefipour +5
Nearly quantum limited Josephson parametric amplifiers (JPAs) are essential components in superconducting quantum circuits. However, higher order nonlinearities of the Josephson co…
