Coulomb collisions of hot and cold single electrons in series-coupled silicon single-electron pumps
Gento Yamahata, Nathan Johnson, Akira Fujiwara
Control of the Coulomb interaction between single electrons is vital for realizing quantum information processing using flying electrons and, particularly, for the realization of d…
A high-fidelity quantum matter-link between ion-trap microchip modules
M. Akhtar, F. Bonus, F. R. Lebrun-Gallagher +7
System scalability is fundamental for large-scale quantum computers (QCs) and is being pursued over a variety of hardware platforms. For QCs based on trapped ions, architectures su…
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…
Energy relaxation in hot electron quantum optics via acoustic and optical phonon emission
Clive Emary, Lewis A. Clark, Masaya Kataoka +1
We study theoretically the relaxation of hot quantum-Hall edge-channel electrons under the emission of both acoustic and optical phonons. Aiming to model recent experiments with si…
