| Abstract: | The concurrence of a two-qubit nonorthogonal pure state is determined through the construction of this state in the language of spin coherent states. The generalization of this method to the case of a class of mixed states is given. The concurrence in this case is nothing but a function of the amplitude of the spin coherent states, it is shown also that probability present an interesting behavior. |
