Based on a particle-hole transformation which is made suitable for non-equilibrium situation, we treat the pair tunneling and cotunneling on an equal footing. We propose an experimental setup to enhance the visibility of pair tunneling, which has no Franck-Condon suppression. We also discuss the shot noise characteristics.5 pages, 4 figures; many changes in title, text, and figuresMesoscale and Nanoscale PhysicsStrongly Correlated Electronstext
