Correlated quasiparticle poisoning from phonon-only events in superconducting qubits
E. Yelton, C. P. Larson, K. Dodge +2
Throughout multiple cooldowns we observe a power-law reduction in time for the rate of multi-qubit correlated poisoning events, while the rate of shifts in qubit offset-charge rema…
Quasiparticle poisoning of superconducting qubits with active gamma irradiation
C. P. Larson, E. Yelton, K. Dodge +5
When a high-energy particle, such as a -ray or muon, impacts the substrate of a superconducting qubit chip, large numbers of electron-hole pairs and phonons are created. The ens…
Low-loss Nb on Si superconducting resonators from a dual-use spintronics deposition chamber and with acid-free post-processing
Maciej W. Olszewski, Jadrien T. Paustian, Tathagata Banerjee +13
Magnetic impurities are known to degrade superconductivity. For this reason, physical vapor deposition chambers that have previously been used for magnetic materials have generally…
