A cm-wave quantum noise limited resonant superconducting parametric amplifier
V. Gilles, T. Sweetnam, B. Mohammadian +2
Superconducting Parametric Amplifiers (SPAs) have seen great interest in recent years due to their high gain and quantum limited noise performance. Among these amplifiers, resonant…
Measuring the Kapitza Resistance between a Passivated Semiconductor and Liquid Helium
Babak Mohammadian, Mark A. McCulloch, Valerio Gilles +2
In this paper, we describe an experimental investigation into the effect of passivation layer thickness on heat dissipation between a quartz substrate and liquid helium. We have ob…
The Impact of Surface Passivation on Kapitza Resistance at the Interface between a Semiconductor and Liquid Nitrogen
Babak Mohammadian, Mark A. McCulloch, Thomas Sweetnam +2
Cooling electronic devices to cryogenic temperatures (< 77 K) is crucial in various scientific and engineering domains. Efficient cooling involves the removal of heat generated fro…
Parametric amplification via superconducting contacts in a Ka band niobium pillbox cavity
Valerio Gilles, Danielius Banys, Mark A. McCulloch +2
Superconducting parametric amplifiers are commonly fabricated using planar transmission lines with a non-linear inductance provided by either Josephson junctions or the intrinsic k…
Simulating the behaviour of travelling wave superconducting parametric amplifiers using a commercial circuit simulator
T. Sweetnam, D. Banys, V. Gilles +2
Kinetic inductance travelling wave parametric amplifiers (KI-TWPAs) have been simulated using Keysight's Advanced Design System (ADS). A lumped element representation of a supercon…
Millimetre Wave Kinetic Inductance Parametric Amplification using Ridge Gap Waveguide
Danielius Banys, Mark Anthony McCulloch, Thomas Sweetnam +2
We present the design and simulation methodology of a superconducting ridge-gap waveguide (RGWG) as a potential basis for mm-wave kinetic inductance travelling wave parametric ampl…
