Cloning a real d-dimensional quantum state on the edge of the no-signaling condition
Patrick Navez, Nicolas J. Cerf
We investigate a new class of quantum cloning machines that equally duplicate all real states in a Hilbert space of arbitrary dimension. By using the no-signaling condition, namely…

Cloning the entanglement of a pair of quantum bits
Louis-Philippe Lamoureux, Patrick Navez, Jaromir Fiurasek +1
It is shown that any quantum operation that perfectly clones the entanglement of all maximally-entangled qubit pairs cannot preserve separability. This ``entanglement no-cloning''…
