The motion of a single vortex is able to originate chaos in the quantum trajectories defined in Bohm's interpretation of quantum mechanics. In this letter, we show that this is also the case in the general situation, in which many interacting vortices exist. This result gives support to those studies in which the Born's probability rule is considered from the point of view of a thermal analogy.
