The combined effects of coherence and interaction on the statistics of tunneling events and the shot noise in a superconducting single-electron transistor (SET) were studied. It was found that the number of distribution of tunneled electrons deviates from the classical Poisson distribution and that zero-frequency shot noise is suppressed significantly due to the coherent oscillation of Cooper pairs in the presence of Coulomb blockade.
