  In this paper, we investigate comparatively the behaviors of quantum discord
and concurrence for Werner states based on two bipartite entangled squeezed
states. The maximally entangled squeezed states are regarded as a
perfect-Werner states, while the non-maximally entangled squeezed states are
called quasi-Werner states. We show that, the behavior of the quantum
correlations keep unchanged for these two types of states. However, the quantum
correlations amount presents in perfect-Werner states is very higher than that
presents in quasi-Werner ones. Furthermore, we show that for large values of
squeezed parameter the quasi-Werner states approaches the perfect-Werner states
qualitatively and quantitatively.
