Derivation of potential profile of a dynamic quantum dot
Nathan Johnson, Gento Yamahata, Akira Fujiwara
We report a method to derive the potential barrier profile shape in a dynamic quantum dot and show the loading statistics, and hence accuracy of electron transfer, depend significa…

Picosecond coherent electron motion in a silicon single-electron source
Gento Yamahata, Sungguen Ryu, Nathan Johnson +3
Understanding ultrafast coherent electron dynamics is necessary for application of a single-electron source to metrological standards, quantum information processing, including ele…

Continuous-Variable Tomography of Solitary Electrons
J. D. Fletcher, N. Johnson, E. Locane +7
A method for characterising the wave-function of freely-propagating particles would provide a useful tool for developing quantum-information technologies with single electronic exc…
