Quasiparticle dynamics in a superconducting qubit irradiated by a localized infrared source
Rodrigo Benevides, Maxwell Drimmer, Giacomo Bisson +5
A known source of decoherence in superconducting qubits is the presence of broken Cooper pairs, or quasiparticles. These can be generated by high-energy radiation, either present i…
