We report our studies of zero-frequency shot noise in tunneling through a
parallel-coupled quantum dot interferometer by employing number-resolved
quantum rate equations. We show that the combination of quantum interference
effect between two pathways and strong Coulomb repulsion could result in a
giant Fano factor, which is controllable by tuning the enclosed magnetic flux.
