dc.description.abstractIn this paper, we investigate two different entanglement measures, the negativity and concurrence, in the case of pure and mixed states of two-qubit system basing on the spin coherent states. For two-qubit pure states, the negativity is the same as the concurrence. For mixed states, using a simplified expression of concurrence in Wootters’ measure of entanglement, we write the bounds of Verstraete et al.1 as a function of some new parameters and we compare the both measures for a class of mixed states.en_US
