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.
