Crystalline Germanium Josephson Junctions
Frederik H. Knudsen, Axel Leblanc, Patrick J. Strohbeen +8
Conventional superconducting quantum electronics rely on well-established Josephson junctions made of Al/AlO where the weak link AlO is amorphous and is believed to hos…

Observation of Critical Current Minimum in Super-Honeycomb Josephson Junction Arrays
Melissa Mikalsen, Alexander-Georg Penner, Samuel D. Escribano +6
Superconductor-semiconductor Josephson junction arrays are a uniquely tunable platform for studying collective quantum phenomena, particularly in the regime where localized Andreev…

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…
