A Stress Induced Source of Phonon Bursts and Quasiparticle Poisoning

Kavli Affiliate: Noah Kurinsky | First 5 Authors: Robin Anthony-Petersen, Andreas Biekert, Raymond Bunker, Clarence L. Chang, Yen-Yung Chang | Summary: The performance of superconducting qubits is degraded by a poorly characterized set of energy sources breaking the Cooper pairs responsible for superconductivity, creating a condition often called "quasiparticle poisoning." Recently, a superconductor with one […]
