Fibre-optics implementation of asymmetric phase-covariant quantum cloner
Lucie Bartuskova, Miloslav Dusek, Antonin Cernoch +2
We present the experimental realization of optimal symmetric and asymmetric phase-covariant 1->2 cloning of qubit states using fiber optics. State of each qubit is encoded into a s…
Experimental phase-covariant cloning of polarization states of single photons
A. Cernoch, L. Bartuskova, J. Soubusta +3
The experimental realization of optimal symmetric phase-covariant 1->2 cloning of qubit states is presented. The qubits are represented by polarization states of photons generated…
Optical implementation of the encoding of two qubits to a single qutrit
Lucie Bartuskova, Antonin Cernoch, Radim Filip +3
We have devised an optical scheme for the recently proposed protocol for encoding two qubits into one qutrit. In this protocol, Alice encodes an arbitrary pure product state of two…
