Optical Quantum Cloning - a Review
Nicolas J. Cerf, Jaromir Fiurasek
After a brief introduction to the quantum no-cloning theorem and its link with the linearity and causality of quantum mechanics, the concept of quantum cloning machines is sketched…
Single-passage read-out of atomic quantum memory
J. Fiurasek, J. Sherson, T. Opatrny +1
A scheme for retrieving quantum information stored in collective atomic spin systems onto optical pulses is presented. Two off-resonant light pulses cross the atomic medium in two…
Separating the classical and quantum information via quantum cloning
M. Ricci, F. Sciarrino, N. J. Cerf +3
An application of quantum cloning to optimally interface a quantum system with a classical observer is presented, in particular we describe a procedure to perform a minimal disturb…
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…
Conditional generation of arbitrary single-mode quantum states of light by repeated photon subtractions
Jaromir Fiurasek, Raul Garcia-Patron, Nicolas J. Cerf
We propose a scheme for the conditional generation of arbitrary finite superpositions of (squeezed) Fock states in a single mode of a traveling optical field. The suggested setup r…
Enhancing the capacity and performance of collective atomic quantum memory
T. Opatrny, J. Fiurasek
Present schemes involving the quantum non-demolition interaction between atomic samples and off-resonant light pulses allow us to store quantum information corresponding to a singl…
