It is demonstrated that the ballistic quantum transport properties of an open quantum dot may be described by an ensemble of spatially correlated virtual classical particles moving within self-avoiding strings. The string paths correspond to ray trajectories. The strings exhibit the necessary properties of self-avoidance, interference and the non-local condition mv · dr=nh. The formalism suggests that numerical simulation of quantum flows may be constructed ab initio by using the string representation.
