Model and Measurements of an Optical Stack for Broadband Visible to Near-IR Absorption in TiN KIDs
K. Kouwenhoven, I. Elwakil, J. van Wingerden +4
Typical materials for optical Kinetic Inductance Detetectors (KIDs) are metals with a natural absorption of 30-50% in the visible and near-infrared. To reach high absorption effici…
Phonon-trapping enhanced energy resolution in superconducting single photon detectors
Pieter J. de Visser, Steven A. H. de Rooij, Vignesh Murugesan +2
A noiseless, photon counting detector, which resolves the energy of each photon, could radically change astronomy, biophysics and quantum optics. Superconducting detectors promise…
Strong Reduction of Quasiparticle Fluctuations in a Superconductor due to Decoupling of the Quasiparticle Number and Lifetime
Steven A. H. de Rooij, Jochem J. A. Baselmans, Vignesh Murugesan +2
We measure temperature dependent quasiparticle fluctuations in a small Al volume, embedded in a NbTiN superconducting microwave resonator. The resonator design allows for read-out…
Direct evidence for Cooper pairing without a spectral gap in a disordered superconductor above
Koen M. Bastiaans, Damianos Chatzopoulos, Jian-Feng Ge +9
The idea that preformed Cooper pairs could exist in a superconductor above its zero-resistance state has been explored for unconventional, interface, and disordered superconductors…
