Abstract
We present a calculation of the quantum mechanical anticorrelation bet ween two electrons each occupying an elongated quantum dot (''quantum dash'') and compare it to the corresponding classical result. A nonzer o anticorrelation arises due to the repulsion between electrons. While the classical system is characterized by a sharp transition in the an ticorrelation function, quantum effects smear out this sharp onset. Th e presence of a strong external magnetic field enhances the particle l ocalization, causing the quantum anticorrelation to approach the class ical limit. Some practical applications are discussed.
