We discuss the Aharonov-Bohm effect in terms of the trajectory interpretation of the quantum theory introduced by one of us (DB) and show that the fringe shift is explained as arising from the quantum potential. The role of the vector potential is that of an intermediary which connects the quantum potential to the flux line in a localizable way. This approach is seen to provide further insight into the meaning of the AB effect, by making possible a visualizable representation of how the slit system produces the interference pattern and how this pattern is affected by the flux line.

We re-examine the notion of the quantum potential introduced by the Broglie and Bohm and calculate its explicit form in the case of the two-slit interference experiment. We also calculate the ensemble of particle trajectories through the two slits. The results show clearly how the quantum potential produces the bunching of trajectories that is required to obtain the usual fringe intensity pattern. Hence we are able to account for the interference fringes while retaining the notion of a well-defined particle trajectory. The wider implications of the quantum potential particularly in regard to the quantum interconnectedness are discussed.
