Teleportation scheme implementing the Universal Optimal Quantum Cloning Machine and the Universal NOT gate
arXiv:quant-ph/0304070
Abstract
The universal quantum cloning machine and the universal NOT gate acting on a single qubit can be implemented very generally by slightly modifying the protocol of quantum state teleportation. The experimental demonstration of the 1 to 2 cloning process according to the above scheme has been realized for a qubit encoded in photon polarization.
