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…

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…
