Kondo cloud conductance in cavity-coupled quantum dots with asymmetric barriers
D. Fossion, V. Champain, S. Mohapatra +9
The Kondo effect emerges when a localized spin is screened by conduction electrons, giving rise to a strongly-correlated many-body ground state. In this work, we investigate this p…
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…
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…
