Query: Observation of vanishing charge dispersion of a nearly-open
  superconducting island   Isolation from the environment determines the extent to which charge is
confined on an island, which manifests as Coulomb oscillations such as charge
dispersion. We investigate the charge dispersion of a nanowire transmon hosting
a quantum dot in the junction. We observe rapid suppression of the charge
dispersion with increasing junction transparency, consistent with the predicted
scaling law which incorporates two branches of the Josephson potential. We find
improved qubit coherence times at the point of highest suppression, suggesting
novel approaches for building charge-insensitive qubits.
