Non-equilibrium Quasiparticles in Superconducting Quantum Circuits
Time: 10:00 am
Place: 5310 Chamberlin Hall
Speaker: Prof. Eli Levenson-Falk, University of Southern California
Abstract: Superconducting electrical circuits are an exciting quantum information technology platform. However, quasiparticles--electron-like single-particle excitations of the superconducting condensate--can cause loss and noise, limiting the performance of these devices. The generation mechanisms, behavior, and annihilation channels of these quasiparticles are still poorly understood, hindering efforts to eliminate them from circuits. I will review the evidence for different quasiparticle models, show measurements using Andreev bound states as quasiparticle traps, and discuss future experiments that will determine the best ways to mitigate the harmful effects of quasiparticles.
