Effect of Buried-Interface Preparation for Nb Superconducting Resonators on InP
Logan S. Kusher, Ding Peng, Zihua Zhu +14
Substrate surface preparation is a key step in the fabrication of electronic devices. In III--V semiconductor platforms, e.g. used in HEMTs and lasers, removal of the native substr…
Observation of Critical Current Minimum in Super-Honeycomb Josephson Junction Arrays
Melissa Mikalsen, Alexander-Georg Penner, Samuel D. Escribano +5
Superconductor-semiconductor Josephson junction arrays are a uniquely tunable platform for studying collective quantum phenomena, particularly in the regime where localized Andreev…
Interplay of superconductivity and ferromagnetism in ferromagnetic semiconductor-based Josephson junctions
Hirotaka Hara, Lukas Baker, Axel Leblanc +8
The interplay between superconductivity and ferromagnetism has long been pursued as a route to unconventional Josephson effects, yet suitable material platforms remain limited. Her…
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…
Enhanced superconducting diode effect in hybrid Josephson junctions
Peng Yu, Han Fu, William F. Schiela +7
The superconducting diode effect (SDE) has recently been observed in various systems, sparking interest in novel superconducting devices and offering a new platform to probe intrin…
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…
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…
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…
