Quasiparticle poisoning of superconducting qubits with active gamma irradiation
C. P. Larson, E. Yelton, K. Dodge +5 more·Mar 10, 2025
When a high-energy particle, such as a $\gamma$-ray or muon, impacts the substrate of a superconducting qubit chip, large numbers of electron-hole pairs and phonons are created. The ensuing dynamics of the electrons and holes changes the local offset...
