Andreev-enhanced conductance quantization and gate-tunable induced superconducting gap in germanium
Elyjah Kiyooka, Chotivut Tangchingchai, Gonzalo Troncoso Fernandez-Bada +8
Ge/SiGe quantum well heterostructures confining a high-mobility two-dimensional hole gas (2DHG) have emerged as a compelling platform for hybrid superconductor(S)-semiconductor(Sm)…

Gatemon qubit on a germanium quantum-well heterostructure
Elyjah Kiyooka, Chotivut Tangchingchai, Leo Noirot +9
Gatemons are superconducting qubits resembling transmons, with a gate-tunable semiconducting weak link as the Josephson element. Here, we report a gatemon device featuring an alumi…
