Quantum error thresholds for gauge-redundant digitizations of lattice field theories

Kavli Affiliate: Marcela Carena | First 5 Authors: Marcela Carena, Henry Lamm, Ying-Ying Li, Wanqiang Liu, | Summary: In the quantum simulation of lattice gauge theories, gauge symmetry can be either fixed or encoded as a redundancy of the Hilbert space. While gauge-fixing reduces the number of qubits, keeping the gauge redundancy can provide code […]

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 […]
