Аннотация
The separable mixed two-qubit X-states are classified in accordance with the degeneracies in the spectrum of density matrices. It is shown that there are four classes of separable X-states, among them: one four-dimensional family, a pair of two-dimensional families, and a single zero-dimensional maximally mixed state.
