17 Jun 2007 | Abstract: | We discuss the exact cloning of orthogonal but entangled qubits under local
operations and classical communication. The amount of entanglement necessary in
blank copy for such a cloning is obtained. In particular, to clone any three
Bell states, log2 3 ebit is necessary. For nonmaximally entangled state this
amount is given in form of inequalities. Specifically, any two equal but
non-maximally entangled states need more entangled (than the original) blank
copy. | Source: | arXiv, arxiv.0706.2459 | Services: | Forum | Review | PDF | Favorites |
