Abstract

We compare the maximum achievable polarization correlations for classical-like separable states and quantum entangled states. For one-photon systems we find that the maximally entangled states have three times larger correlations than the maximum correlations achievable with separable states. However, for larger photon numbers we find that there are separable states with larger correlations than the maximally entangled states.
