摘要
We show that a mixed state rho = Sigma(mn) a(mn) \m > < n\ can be realized by an ensemble of pure states {pk, \phi k >} where \phi > = Sigma(mn) root a(mn)e(i theta mk)\m. 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.
