| Abstract: | We study the nonlocal correlations and quantum entanglement for two deformed bosonic fields of arbitrary deformation parameters, q 1 and q 2, prepared in an entanglement of deformed coherent states. As a measure of entanglement, we use the von Neumann entropy and investigate its behavior for different strength regimes of the optical fields. We find that the photon number can enhance the von Neumann entropy, and the deformation parameters can restrain the system entanglement. |
