Aalto University have, in addition to cryogenic experiments on nano-electronic devices in general, strong expertise on single-charge pumping with three arbitrary waveforms, which may be employed in increasing the robustness of electron pumping. Furthermore, Aalto has the most experience on measuring silicon quantum dots fabricated by the University of New South Wales, including recent results on single-electron counting. This expertise will be fully employed in this project. Aalto will contribute to high-accuracy measurements of Si pumps in this project.
