Abstract

We have investigated the effect of shot noise on the IV-curves of a single Coulomb blockaded Josephson junction. We observe a linear enhancement of zero-bias conductance of the Josephson junction as a function of the shot noise power induced with a normal-insulating-superconducting tunnel junction directly coupled to the island. With increasing shot noise power, the IV-curves becomes asymmetric with a shift of minimum conductance and the appearance of a local conductance maximum. The asymmetry shows that the Coulomb blockade of Cooper pairs is strongly influenced by the non-Gaussian character of the shot noise.
