    "abstract": "Local quantum operations and classical communication (LOCC) put considerable\nconstraints on many quantum information processing tasks such as cloning and\ndiscrimination. Surprisingly however, discrimination of any two pure states\nsurvives such constraints in some sense. In this paper, we show that cloning is\nnot that lucky; namely, conclusive LOCC cloning of two product states is\nstrictly less efficient than global cloning.",
