In addition to the main Coulomb blockade diamonds, &quot;shadow&quot; diamonds appear, shifted by 1e in gate voltage, consistent with transport through an excited (poisoned) state of the island. Comparison to a simple model yields an estimate of parity lifetime for the strongly coupled island (∼1 μs) and sets a bound for a weakly coupled island (&gt;10 μs). Fluctuations in the gate-voltage spacing of Coulomb peaks at high field, reflecting Majorana hybridization, are enhanced by the reduced lever arm at strong coupling. When converted from gate voltage to energy units, fluctuations are consistent with previous measurements."}],"oa_version":"Preprint","date_published":"2017-03-31T00:00:00Z","external_id":{"arxiv":["1612.05748"]},"author":[{"full_name":"Albrecht, S M","last_name":"Albrecht","first_name":"S M"},{"full_name":"Hansen, Esben","last_name":"Hansen","first_name":"Esben"},{"full_name":"Higginbotham, Andrew P","last_name":"Higginbotham","id":"4AD6785A-F248-11E8-B48F-1D18A9856A87","orcid":"0000-0003-2607-2363","first_name":"Andrew P"},{"full_name":"Kuemmeth, Ferdinand","last_name":"Kuemmeth","first_name":"Ferdinand"},{"full_name":"Jespersen, Thomas","first_name":"Thomas","last_name":"Jespersen"},{"full_name":"Nygård, Jesper","first_name":"Jesper","last_name":"Nygård"},{"first_name":"Peter","last_name":"Krogstrup","full_name":"Krogstrup, Peter"},{"full_name":"Danon, Jeroen","last_name":"Danon","first_name":"Jeroen"},{"last_name":"Flensberg","first_name":"Karsten","full_name":"Flensberg, Karsten"},{"full_name":"Marcus, Charles","last_name":"Marcus","first_name":"Charles"}],"date_updated":"2021-01-12T06:47:47Z","user_id":"3E5EF7F0-F248-11E8-B48F-1D18A9856A87","year":"2017","_id":"103","quality_controlled":"1","doi":"10.1103/PhysRevLett.118.137701","publication_status":"published","volume":118,"extern":"1","main_file_link":[{"url":"https://arxiv.org/abs/1612.05748","open_access":"1"}],"month":"03","publication":"APS Physics, Physical Review Letters","citation":{"apa":"Albrecht, S.
