Quantum analysis of second-order effects in superconducting travelling-wave parametric amplifiers
Abstract: We have performed a quantum mechanical analysis of travelling-wave parametric amplifiers (TWPAs) in order to investigate five experimental phenomena related to their operations, namely the effect of impedance mismatch...
Strain in heterogeneous quantum devices with atomic layer deposition
Abstract
We investigated the use of dielectric layers produced by atomic layer deposition (ALD) as an approach to strain mitigation in composite silicon/superconductor devices...

Electrothermal feedback in kinetic inductance detectors
In kinetic inductance detectors (KIDs) and other similar applications of superconducting microresonators, both the large and small-signal behaviour of the device may be affected by electrothermal feedback. Microwave power...
Simulation method for investigating the use of transition-edge sensors as spectroscopic electron detectors
Transition-edge sensors (TESs) are capable of highly accurate single particle
energy measurement. TESs have been used for a wide range of photon detection
applications, particularly in astronomy, but very little consideration...
Modelling proximity effects in transition edge sensors to investigate the influence of lateral metal structures
The bilayers of transition edge sensors (TESs) are often modified with additional normal-metal features such as bars or dots. Previous device measurements suggest that these features improve performance, reducing electrical...

Nonlinear mechanisms in Al and Ti superconducting travelling-wave parametric amplifiers
The underlying nonlinear mechanisms behind the operation of travelling-wave
parametric amplifiers (TWPAs) are important in determining their performance in
terms of added noise, maximum gain, and bandwidth. We describe a method...

We present evidence for Cp* being a sacrificial placeholder ligand in the [Cp*IrIII(chelate)X] series of homogeneous oxidation catalysts. UV-vis and 1H-NMR profiles as well as MALDI-MS data show a rapid and irreversible loss of...
