--- _id: '103' abstract: - lang: eng text: We investigate effects of quasiparticle poisoning in a Majorana island with strong tunnel coupling to normal-metal leads. In addition to the main Coulomb blockade diamonds, "shadow" 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 (>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. acknowledgement: Research supported by Microsoft, the Danish National Research Foundation, the Lundbeck Foundation, Carlsberg Foundation, Villum Foundation, and the European Commission. article_number: '137701' author: - first_name: S M full_name: Albrecht, S M last_name: Albrecht - first_name: Esben full_name: Hansen, Esben last_name: Hansen - first_name: Andrew P full_name: Higginbotham, Andrew P id: 4AD6785A-F248-11E8-B48F-1D18A9856A87 last_name: Higginbotham orcid: 0000-0003-2607-2363 - first_name: Ferdinand full_name: Kuemmeth, Ferdinand last_name: Kuemmeth - first_name: Thomas full_name: Jespersen, Thomas last_name: Jespersen - first_name: Jesper full_name: Nygård, Jesper last_name: Nygård - first_name: Peter full_name: Krogstrup, Peter last_name: Krogstrup - first_name: Jeroen full_name: Danon, Jeroen last_name: Danon - first_name: Karsten full_name: Flensberg, Karsten last_name: Flensberg - first_name: Charles full_name: Marcus, Charles last_name: Marcus citation: ama: Albrecht SM, Hansen E, Higginbotham AP, et al.
