Local cloning of CAT states
arXiv:1008.2889 · doi:10.1016/j.physleta.2011.04.050
Abstract
In this Letter we analyze the (im)possibility of the exact cloning of orthogonal three-qubit CAT states under local operation and classical communication(LOCC) with the help of a restricted entangled state. We also classify the three-qubit CAT states that can(not) be cloned under LOCC restrictions and extend the results to the n-qubit case.
