  text: Quasiparticle excitations can compromise the performance of superconducting
    devices, causing high-frequency dissipation, decoherence in Josephson qubits,
    and braiding errors in proposed Majorana-based topological quantum computers.
    Quasiparticle dynamics have been studied in detail in metallic superconductors
    but remain relatively unexplored in semiconductor-superconductor structures, which
    are now being intensely pursued in the context of topological superconductivity.
    To this end, we use a system comprising a gate-confined semiconductor nanowire
    with an epitaxially grown superconductor layer, yielding an isolated, proximitized
    nanowire segment. We identify bound states in the semiconductor by means of bias
    spectroscopy, determine the characteristic temperatures and magnetic fields for
    quasiparticle excitations, and extract a parity lifetime (poisoning time) of the
    bound state in the semiconductor exceeding 10 ms.
