Nonequilibrium regimes for quasiparticles in superconducting qubits with gap-asymmetric junctions
G. Marchegiani, G. Catelani
Superconducting qubits hold promise for quantum computing, but their operation is challenged by various sources of noise, including excitations known as quasiparticles. Qubits with…
Quasiparticle effects in magnetic-field-resilient 3D transmons
J. Krause, G. Marchegiani, L. M. Janssen +3
Recent research shows that quasiparticle-induced decoherence of superconducting qubits depends on the superconducting-gap asymmetry originating from the different thicknesses of th…
Magnetic-field dependence of a Josephson traveling-wave parametric amplifier and integration into a high-field setup
L. M. Janssen, G. Butseraen, J. Krause +6
We investigate the effect of magnetic field on a photonic-crystal Josephson traveling-wave parametric amplifier (TWPA). We show that the observed change in photonic bandgap and pla…
Nonequilibrium quasiparticle distribution in superconducting resonators: effect of pair-breaking photons
P. B. Fischer, G. Catelani
Many superconducting devices rely on the finite gap in the excitation spectrum of a superconductor: thanks to this gap, at temperatures much smaller than the critical one the numbe…
