Volume dependence of microwave induced excess quasiparticles in superconducting resonators
Steven A. H. de Rooij, Jochem J. A. Baselmans, Juan Bueno +3
The presence of quasiparticles typically degrades the performance of superconducting microwave circuits. The readout signal can generate non-equilibrium quasiparticles, which lead…
Recombination of localized quasiparticles in disordered superconductors
Steven A. H. de Rooij, Remko Fermin, Kevin Kouwenhoven +6
Disordered superconductors offer new impedance regimes for quantum circuits, enable a pathway to protected qubits, and can improve superconducting detectors due to their high kinet…
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…
Reactive magnetron sputter deposition of superconducting niobium titanium nitride thin films with different target sizes
B. G. C. Bos, D. J. Thoen, E. A. F. Haalebos +4
The superconducting critical temperature (Tc > 15K) of niobium titanium nitride (NbTiN) thin films allows for low-loss circuits up to 1.1 THz, enabling on-chip spectroscopy and mul…
