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."}],"date_published":"2015-09-14T00:00:00Z","extern":"1","publication_status":"published","issue":"12","month":"09","date_updated":"2021-01-12T08:22:28Z","type":"journal_article","day":"14","title":"Parity lifetime of bound states in a proximitized semiconductor nanowire","quality_controlled":"1","status":"public","publisher":"Nature Publishing Group","oa":1,"oa_version":"Preprint","user_id":"3E5EF7F0-F248-11E8-B48F-1D18A9856A87","date_created":"2018-12-11T11:44:37Z","language":[{"iso":"eng"}],"_id":"99","citation":{"short":"A.P.
