    "abstract": "It is shown that for each mixed state there exists a Schmidt (super state\nvector) decomposition in terms of Hermitian operators. Its utilization for\nfinding all twins is illustrated in full detail in the case of the two\nspin-one-half-particle states with maximally disordered subsystems (mixtures of\nBell states).",
