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…
Optimal operation of hole spin qubits
Marion Bassi, Esteban-Alonso Rodrıguez-Mena, Boris Brun +11
Hole spins in silicon or germanium quantum dots have emerged as a compelling solid-state platform for scalable quantum processors. Besides relying on well-established manufacturing…
Parametric longitudinal coupling of a semiconductor charge qubit and a RF resonator
Victor Champain, Simon Zihlmann, Alessandro Chessari +11
In this study, we provide a full experimental characterization of the parametric longitudinal coupling between a CMOS charge qubit and an off-chip RF resonator. Following Corrigan…
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…
Real-time milli-Kelvin thermometry in a semiconductor qubit architecture
Victor Champain, Vivien Schmitt, Benoit Bertrand +6
We report local time-resolved thermometry in a silicon nanowire quantum dot device designed to host a linear array of spin qubits. Using two alternative measurement schemes based o…
