Quasiparticle Dynamics in Epitaxial Al – In As Planar Josephson Junctions
Using locally injected and thermal quasiparticles, we study QP loss and QP poisoning in epitaxial Al-InAs Josephson junctions incorporated in a superconducting quantum interference device (SQUID) galvanically shorting a superconducting resonator to ground. We observe changes in the resonance lineshape and frequency shifts consistent with QP trapping into and clearing out of the ABSs of …
