    "abstract": "The impossibility to clone an unknown quantum state is a powerful principle\nto understand the nature of quantum mechanics, especially within the context of\nquantum computing and quantum information. This principle has been generalized\nto quantitative statements as to what extent imperfect cloning is possible. We\ndelineate an aspect of the border between the possible and the impossible\nconcerning quantum cloning, by putting forward an entanglement-assisted scheme\nfor simulating perfect cloning in the context of weak measurements. This\nphenomenon we call weak cloning of an unknown quantum state.",
