Modeling Phonon-mediated Quasiparticle Poisoning in Superconducting Qubit Arrays

Kavli Affiliate: Noah Kurinsky | First 5 Authors: Eric Yelton, Clayton P. Larson, Vito Iaia, Kenneth Dodge, Guglielmo La Magna | Summary: Correlated errors caused by ionizing radiation impacting superconducting qubit chips are problematic for quantum error correction. Such impacts generate quasiparticle (QP) excitations in the qubit electrodes, which temporarily reduce qubit coherence significantly. The […]
