Abstract:	We show that a mixed state = _mna_mn\|mn\| can be realized by an ensemble of pure states {p_k, \|_k} where $\|\Phi _k \rangle = \sum _m \sqrt {a_{mm} } e^{i\theta _m^k } \|m\rangle$ . Employing this form, we discuss the relative entropy of entanglement of Schmidt correlated states. Also, we calculate the distillable entanglement of a class of mixed states.
