Highly asymmetric quantum cloning in arbitrary dimension
Jaromir Fiurasek, Radim Filip, Nicolas J. Cerf
We investigate the universal asymmetric cloning of states in a Hilbert space of arbitrary dimension. We derive the class of optimal and fully asymmetric 1->3 cloners, which produce…

Partial deterministic non-demolition Bell measurement
Ladislav Mišta, Radim Filip
We propose the scheme implementing partial deterministic non-demolition Bell measurement. When it is used in quantum teleportation the information about an unknown input state is o…

Knowledge excess duality and violation of Bell inequalities
R. Filip, M. Gavenda
A constraint on two complementary knowledge excesses by maximal violation of Bell inequalities for a single copy of any mixed state of two qubits is analyzed. The complementa…
