Sebastien Granel, Frederic Gustavo, Jean-Luc Thomassin +8
The paper demonstrates a 3D‑integrated hybrid circuit QED device that combines silicon MOS quantum dots with superconducting NbN resonators, achieving fast gate‑based charge readou…
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)…
A hole spin resilient to dipole-induced thermal effects
V. Champain, G. Boschetto, H. Niebojewski +12
Recent advances in scaling up spin-based quantum processors have revealed unanticipated issues related to thermal effects. Microwave pulses required to manipulate and read the qubi…
Coherence of a hole spin flopping-mode qubit in a circuit quantum electrodynamics environment
Léo Noirot, Cécile X. Yu, José C. Abadillo-Uriel +5

Unifying Floquet theory of longitudinal and dispersive readout
Alessandro Chessari, Esteban A. RodrÃguez-Mena, José Carlos Abadillo-Uriel +5
We devise a Floquet theory of longitudinal and dispersive readout in circuit QED. By studying qubits coupled to cavity photons and driven at the resonance frequency of the cavity $…
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…
