Efficient flip-chip and on-chip-based modulation of flux-tunable superconducting resonators
Achintya Paradkar, Paul Nicaise, Karim Dakroury +5
We demonstrate the efficient modulation of flux-tunable superconducting resonators (FTRs) using flip-chip or on-chip-based input coils. The FTRs we use are aluminum-based quarter-w…
Superconducting flip-chip devices using indium microspheres on Au-passivated Nb or NbN as under-bump metallization layer
Achintya Paradkar, Paul Nicaise, Karim Dakroury +2
Superconducting flip-chip interconnects are crucial for the three-dimensional integration of superconducting circuits in sensing and quantum technology applications. We demonstrate…
Investigation of reflection-based measurements of microwave kinetic inductance detectors in the optical bands
Jie Hu, Faouzi Boussaha, Paul Nicaise +4
In this paper, we investigate the single photon response from the reflection of the Microwave Kinetic Inductance Detector (MKID) array. Reflection measurements are carried out usin…
Design and Simulation of TiN-Based Suspended Meander Kinetic Inductance Detectors (KIDs) for Visible and Near-Infrared Astronomy Applications
Maria Appavou, Lucas Ribeiro, Paul Nicaise +6
We report on simulations of a novel design of optical titanium nitride (TiN)- based Kinetic Inductance Detectors (KIDs) in order to improve their response to optical photons. We pr…
Investigation of Quasi-particle Relaxation in Strongly Disordered Superconductor Resonators
Jie Hu, Jean-Marc Matin, Paul Nicaise +5
In this paper, we investigate the quasi-particle (QP) relaxation of strongly disordered superconducting resonators under optical illumination at different bath temperatures with th…
