Hybrid superinductance with Al/InAs
Junseok Oh, Ido Levy, Tyler Cowan +4
We report microwave spectroscopy of Josephson junctions chains made from an epitaxial Al/InAs heterostructure. The chains exhibit superinductance, with characteristic wave impedanc…
Strongly anharmonic flux-tunable transmon based on InAs-Al 2D heterostructure
Shukai Liu, Arunav Bordoloi, Jacob Issokson +4
The gatemon qubits, made of transparent superconducting-semiconducting Josephson junctions, typically have even weaker anharmonicity than the opaque AlOx-junction transmons. Howeve…
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 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…
Molecular beam epitaxy growth of superconducting tantalum germanide
Patrick J. Strohbeen, Tathagata Banerjee, Aurelia M. Brook +7
Developing new material platforms for use in superconductor-semiconductor hybrid structures is desirable due to limitations caused by intrinsic microwave losses present in commonly…
Andreev reflection of quantum Hall states through a quantum point contact
Mehdi Hatefipour, Joseph J. Cuozzo, Ido Levy +4
We investigate the interplay between the quantum Hall (QH) effect and superconductivity in InAs surface quantum well (SQW)/NbTiN heterostructures using a quantum point contact (QPC…
Characterizing losses in InAs two-dimensional electron gas-based gatemon qubits
William M. Strickland, Lukas J. Baker, Jaewoo Lee +9
The tunnelling of cooper pairs across a Josephson junction (JJ) allow for the nonlinear inductance necessary to construct superconducting qubits, amplifiers, and various other quan…
