Sapphire whispering gallery mode resonators at millikelvin temperature
Daniel L. Creedon,Yarema Reshitnyk,Jean-Michel Le Floch,Warrick G. Farr,John M. Martinis,Tim Duty,Michael E. Tobar +6 more
TL;DR: In this paper, the authors reported the first cooling of a bulk sapphire sample below super fluid liquid helium temperature (1.6K) to as low as 25mK.
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.
Proceedings Article

Michael E. Tobar,Eugene Ivanov,Daniel L. Creedon,Jean-Michel Le Floch,Karim Benmessai,Yaohui Fan,Warrick G. Farr,Yarema Reshitnyk,Tim Duty,John M. Martinis +9 more
TL;DR: The Frequency Standards and Metrology Research Group at the University of Western Australia have been developing some of the world's most ultra-precise measurements at microwave frequencies since the 1990s as discussed by the authors.
Phase transformation-induced superconducting aluminium-silicon alloy rings
B. C. Johnson,Michael Stuiber,Daniel L. Creedon,Amanuel M. Berhane,L. H. Willems van Beveren,Sergey Rubanov,Jared H. Cole,Vincent Mourik,Alex R. Hamilton,Tim Duty,Jeffrey C. McCallum +10 more
TL;DR: In this article , the formation of superconductivity in nanowires fabricated with silicon-on-insulator (SOI) was investigated, and the phase transformed material is conformal with any predefined device patterns and the resultant structures are exceptionally smooth-walled compared to similar nanowire devices formed by silicidation processes.
Journal Article
Magnetic-field-induced parity effect in insulating Josephson junction chains
TL;DR: In this paper, even-odd parity effects in the transport characteristics of insulating Josephson junction chains which occur as the superconducting gap is suppressed by applied magnetic fields at millikelvin temperatures were investigated.
