  We study systems of two identical dipolar particles confined in quasi
one-dimensional harmonic traps. Numerical results for the dependencies of the
entanglement on the control parameters of the systems are provided and
discussed in detail. In the limit of a strong interaction between the
particles, the occupancies and the von Neumann entropies of the bosonic and
fermionic ground states are derived in closed analytic forms by applying the
harmonic approximation. The strong correlation regimes of the system with the
dipolar bosons and the system with the charged ones are compared with each
other in regard to aspects of their entanglement.
