Origins of microwave losses in superconducting circuits made with silicon-on-insulator substrates
Simon Messelot, Nicolas Aparicio, Kazi Rafsanjani Amin +11
Silicon-on-insulator technology is widely used to fabricate silicon based devices, from advanced transistors to photonic circuits or nanomechanical systems. Integrating low loss su…
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)…
Coherence Limits in Interference-Based cos(2) Qubits
S. Messelot, A. Leblanc, J. -S. Tettekpoe +4
We investigate the coherence properties of parity-protected qubits based on interferences between two Josephson elements in a superconducting loop. We show that qubit im…
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…
Gate- and flux-tunable sin(2) Josephson element with proximitized Ge-based junctions
Axel Leblanc, Chotivut Tangchingchai, Zahra Sadre Momtaz +11
Hybrid superconductor-semiconductor Josephson field-effect transistors (JoFETs) function as Josephson junctions with a gate-tunable critical current. Additionally, they can feature…
From nonreciprocal to charge-4e supercurrents in Ge-based Josephson devices with tunable harmonic content
Axel Leblanc, Chotivut Tangchingchai, Zahra Sadre Momtaz +10
Hybrid superconductor(S)-semiconductor(Sm) devices bring a range of new functionalities into superconducting circuits. In particular, hybrid parity-protected qubits and Josephson d…
