Coulomb sensing of single ballistic electrons
J. D. Fletcher, W. Park, P. See +6
While ballistic electrons are a key tool for applications in sensing and flying qubits, sub-nanosecond propagation times and complicated interactions make control of ballistic sing…
Statistical study and parallelisation of multiplexed single-electron sources
S. Norimoto, P. See, N. Schoinas +7
Increasing electric current from a single-electron source is a main challenge in an effort to establish the standard of the ampere defined by the fixed value of the elementary char…
Photon emission by hot electron injection across a lateral \textit{pn} junction
S. Norimoto, R. Saxena, P. See +5
We demonstrate a method to generate photons by injecting hot electrons into a {\it pn} junction within a \ce{GaAs/AlGaAs} heterostructure. Hot electrons are generated by biasing ac…
Fast characterization of multiplexed single-electron pumps with machine learning
N. Schoinas, Y. Rath, S. Norimoto +8
We present an efficient machine learning based automated framework for the fast tuning of single-electron pump devices into current quantization regimes. It uses a sparse measureme…
