Journal ArticleDOI
Parity effect and single-electron injection for Josephson-junction chains deep in the insulating state
TL;DR: In this paper, a systematic investigation of charge transport in one-dimensional chains of Josephson junctions was made, where the characteristic Josephson energy is much less than the single-junction Cooper-pair charging energy, EJ-ECP.
Patent
Phase shift device in superconductor logic
Geordie Rose,Mohammad H. Amin,Tim Duty,Alexandre M. Zagoskin,A. N. Omelyanchouk,Jeremy P. Hilton +5 more
TL;DR: In this paper, a phase shift device can be used in superconducting quantum computing circuitry, where the phase shift between the phases of the order parameters of the device's two terminals can be introduced.
Proceedings ArticleDOI
Fast tuning of superconducting microwave cavities
Martin Sandberg,Christopher Wilson,Fredrik Persson,Göran Johansson,Vitaly Shumeiko,Thilo Bauch,Tim Duty,Per Delsing +7 more
TL;DR: In this article, the authors demonstrate superconducting microwave cavities, with tunable effective lengths, obtained by varying a Josephson inductance at one end of the cavity, and demonstrate tuning by several hundred linewidths in a time Delta t << tau.
Journal ArticleDOI
A planar Al-Si Schottky barrier metal-oxide-semiconductor field effect transistor operated at cryogenic temperatures
W. E. Purches,Alessandro Rossi,Ruichen Zhao,Sergey Kafanov,Tim Duty,Andrew S. Dzurak,Sven Rogge,Giuseppe C. Tettamanzi +7 more
TL;DR: In this paper, the gate electrode is selfaligned with the device channel and overlaps the source and drain electrodes, which facilitates a sub-5 nm gap between the source/drain and channel, and no spacers are required.
Journal ArticleDOI
Crossover from time-correlated single-electron tunneling to that of Cooper pairs
TL;DR: In this paper, the authors studied charge transport in a one-dimensional chain of small Josephson junctions using a single-electron transistor and observed a crossover from time-correlated tunneling of single electrons to that of Cooper pairs as a function of both magnetic field and current.
