Thermal transport in nanoelectronic devices cooled by on-chip magnetic refrigeration
S. Autti, F. C. Bettsworth, K. Grigoras +8
On-chip demagnetization refrigeration has recently emerged as a powerful tool for reaching microkelvin electron temperatures in nanoscale structures. The relative importance of coo…
Effects of charge noise on a pulse-gated singlet-triplet qubit
Zhenyi Qi, X. Wu, D. R. Ward +11
We study the dynamics of a pulse-gated semiconductor double quantum dot qubit. In our experiments, the qubit coherence times are relatively long, but the visibility of the quantum…
Transport through an impurity tunnel coupled to a Si/SiGe quantum dot
Ryan H. Foote, Daniel R. Ward, J. R. Prance +8
Achieving controllable coupling of dopants in silicon is crucial for operating donor-based qubit devices, but it is difficult because of the small size of donor-bound electron wave…
Tunable singlet-triplet splitting in a few-electron Si/SiGe quantum dot
Zhan Shi, C. B. Simmons, J. R. Prance +6
We measure the excited-state spectrum of a Si/SiGe quantum dot as a function of in-plane magnetic field, and we identify the spin of the lowest three eigenstates in an effective tw…
