Abstract
The amount of particles that are transported via a path of motion is characterized by its expectation value and by its variance . We analyze what happens if a particle has two optional paths available to get from one site to another site, and in particular what is for the current which is induced in a quantum stirring device. It turns out that coherent splitting and the stirring effect are intimately related and cannot be understood within the framework of the prevailing probabilistic theory.
