  We study the motion of a pair of electrons along two separate parallel chains
of quantum dots. The electrons that are released from the central dot of each
chain tend to accompany and not avoid each other. The correlated electron
motion involves entanglement of the wave functions which is generated in time
upon release of the initial confinement. Observation of the simultaneous
presence of electrons at the same side of the chain can provide fingerprint of
the paired electron motion.
