  Quasiparticle (QP) effects play a significant role in the coherence and
fidelity of superconducting quantum circuits. The Andreev bound states of high
transparency Josephson junctions can act as low-energy traps for QPs, providing
a mechanism for studying the dynamics and properties of both the QPs and the
junction. We study the trapping and clearing of QPs from the Andreev bound
states of epitaxial Al-InAs Josephson junctions incorporated in a
superconducting quantum interference device (SQUID) galvanically shorting a
superconducting resonator to ground. We use a neighboring voltage-biased
Josephson junction to inject QPs into the circuit. Upon the injection of QPs,
we show that we can trap and clear QPs when the SQUID is flux-biased. We
examine effects of the microwave loss associated with bulk QP transport in the
resonator, QP-related dissipation in the junction, and QP poisoning events. By
monitoring the QP trapping and clearing in time, we study the dynamics of these
processes and find a time-scale of few microseconds that is consistent with
electron-phonon relaxation in our system and correlated QP trapping and
clearing mechanisms. Our results highlight the QP trapping and clearing
dynamics as well as the associated time-scales in high transparency Josephson
junctions based fabricated on Al-InAs heterostructures.
