    "abstract": "The no-cloning principle tells us that non-orthogonal quantum states cannot\nbe cloned, but it does not tell us that orthogonal states can always be cloned.\nWe suggest a situation where the cloning transformations are restricted,\nleading to a novel type of no-cloning principle. In the case of a composite\nsystem made of two subsystems: if the subsystems are only available one after\nthe other then there are various cases when orthogonal states cannot be cloned.\nSurprising examples are given, which give a radically better insight regarding\nthe basic concepts of quantum cryptography.",
