abstractNote = {We study the quantum state transfer (QST) in a class of qubit networks with on-site Coulomb interaction, which are described by the generalized Hubbard model with engineered hopping strengths. It is proved that the N-site system of two electrons with opposite spins can be rigorously reduced into N one dimensional engineered single Bloch electron models with central potential barrier. With this observation, we find that such system can perform a perfect QST, the quantum swapping between two distant electrons with opposite spins. Numerical results show that such QST and the resonant tunneling occur for the optimal on-site repulsive interaction.},
