A Spin Quintet in a Silicon Double Quantum Dot: Spin Blockade and Relaxation
Theodor Lundberg, Jing Li, Louis Hutin +12
Spins in gate-defined silicon quantum dots are promising candidates for implementing large-scale quantum computing. To read the spin state of these qubits, the mechanism that has p…

Low-temperature tunable radio-frequency resonator for sensitive dispersive readout of nanoelectronic devices
David J. Ibberson, Lisa A. Ibberson, Geoff Smithson +3
We present a sensitive, tunable radio-frequency resonator designed to detect reactive changes in nanoelectronic devices down to dilution refrigerator temperatures. The resonator in…

Electric-field tuning of the valley splitting in silicon corner dots
David J. Ibberson, Léo Bourdet, José C. Abadillo-Uriel +5
We perform an excited state spectroscopy analysis of a silicon corner dot in a nanowire field-effect transistor to assess the electric field tunability of the valley splitting. Fir…
