Separation out of Entanglement
Abstract
We investigate the separability properties of quantum states described by an extended Werner density matrix, where the classical component exhibits statistical dependence. By generalizing the classical part to allow correlations, we demonstrate that within a specific parameter range the separable region expands compared to the standard Werner state with an independent classical component. This result suggests that increasing classical correlation can enhance the separability of the overall quantum state, providing new insights into the interplay between classical and quantum correlations.
