Advances toward high-accuracy gigahertz operation of tunable-barrier single-hole pumps in silicon
Gento Yamahata, Akira Fujiwara
Precise and reproducible current generation is key to realize quantum current standards in metrology. A promising candidate is a tunable-barrier single-charge pump, which can accur…
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…
Precision measurement of an electron pump at 2 GHz
Stephen Giblin, Gento Yamahata, Akira Fujiwara +1
A well-characterised sample of silicon tunable-barrier electron pump has been operated at a frequency of 2 GHz using a custom drive waveform, generating a pump current of 320 pA. P…
