Abstract
We investigate a double-well tunneling process in Bose condensates of two interacting species. We show that particles of different species can tunnel as pairs through the potential barrier between the two wells in opposite directions. Such a correlated motion of tunneling atoms leads to the generation of quantum entanglement between two macroscopically coherent systems. The strong correlations are manifested in the particle number sum and the phase difference variables.
