    "abstract": "The classical signal splitting and copying are not possible in quantum\nmechanics. Specifically, one cannot copy the basis up and down states of the\ninput (I) two-state system (qubit, spin) into the copy (C) and duplicate-copy\n(D) two-state systems if the latter systems are initially in an arbitrary\nstate. We consider instead a quantum evolution in which the basis states of I\nat time t are duplicated in at least two of the systems I, C, D, at time t +\nDelta t. In essence, the restriction on the initial target states is exchanged\nfor uncertainty as to which two of the three qubits retain copies of the\ninitial source state.",
