"Partial" quantum cloning and quantum cloning of the mixed states
A. Ya. Kazakov
We discuss the "partial" quantum cloning of the pure two-partite states, when the "part" of initial state related to the one qubit is copied only. The same approach gives the possi…

Dense coding and safety of quantum communications
A. Ya. Kazakov
The sending station being the classical device can be eavesdropped by classical means. Dense coding and quantum nature of wave function give the additional resource to raise the sa…
