Controllable tunnelling of single flux-quanta mediated by quantum phase-slip in disordered superconducting loops
Jamie A. Potter, Jonathan C. Fenton, Paul A. Warburton
Quantum phase-slip (QPS) is the exact dual to the well-known Josephson effect. Although there are numerous proposals for applications of QPS devices, experimental work to develop t…
Gate-controlled conductance of superconducting NbN nanowires: coherent quantum phase-slips or Coulomb blockade?
M. S. Anwar, J. C. Fenton
Coherent quantum phase slips are expected to lead to a blockade of dc conduction in sufficiently narrow superconducting nanowires below a certain critical voltage. We present measu…
Nonlinear quantum processes in superconducting resonators terminated by neon-focused-ion-beam-fabricated superconducting nanowires
Jamie A. Potter, Oscar W. Kennedy, Jonathan C. Fenton +1
We have used a neon focused-ion-beam to fabricate both nanoscale Nb Dayem bridges and NbN phase-slip nanowires located at the short-circuited end of quarter-wavelength coplanar wav…
Tunable Nb superconducting resonators based upon a Ne-FIB-fabricated constriction nanoSQUID
Oscar W. Kennedy, Jonathan Burnett, Jonathan C. Fenton +4
Hybrid superconducting--spin systems offer the potential to combine highly coherent atomic quantum systems with the scalability of superconducting circuits. To fully exploit this p…
Emergence of Quantum Phase-Slip Behaviour in Superconducting NbN Nanowires: DC Electrical Transport and Fabrication Technologies
N. G. N. Constantino, M. S. Anwar, O. W. Kennedy +3
Superconducting nanowires undergoing quantum phase-slips have potential for impact in electronic devices, with a high-accuracy quantum current standard among a possible toolbox of…
Low-Loss Superconducting Nanowire Circuits Using a Neon Focused Ion Beam
Jonathan Burnett, James Sagar, Oscar W. Kennedy +2
We present low-temperature measurements of low-loss superconducting nanowire-embedded resonators in the low-power limit relevant for quantum circuits. The superconducting resonator…
