On arXiv: Finite-Bias Coulomb Blockade Thermometry

Temperature is a key parameter in quantum devices, where different degrees of freedom can decouple and exhibit intricate thermodynamics. Coulomb blockade thermometers (CBTs) are versatile and, in principle, primary thermometers operating…

Published in Phys. Rev. Research: Coupling a high-Q resonator to a spin qubit with all-electrical control

High-Q resonators make possible fast spin readout but are susceptible to crosstalk and suffer from ringup due to qubit control pulses. Here, we report on the coherent and all-electrical control of a Si:FinFET hole spin qubit at 1.5 K with a…

On ArXiv: Giant end-tunneling effect in two distinct Luttinger liquids coexisting in one quantum wire

We combine tunneling spectroscopy with density-dependent transport measurements in the same quantum wires over more than two orders of magnitude in temperature to very low temperatures down to ∼40 mK. This reveals that, when the second 1D…
