On arXiv: All-electrical operation of a spin qubit coupled to a high-Q resonator

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…

Published: Cross-Architecture Tuning of Si Qubit Devices using Machine Learning

Device-to-device variability and disorder in spin qubits makes it currently necessary to individually tune each device in a large-dimensional gate space to find the optimal conditions for qubit operation. We take a key step with a…

Published in APL: Prospects of silicide contacts for Si quantum devices

Metal contacts in semiconductor quantum electronic devices can offer advantages over doped contacts, but the formation of a Schottky barrier at the silicon–metal interface can lead to poor contacts at cryogenic temperatures. We investigate…
