Economical quantum cloning in any dimension
Thomas Durt, Jaromir Fiurasek, Nicolas J. Cerf
The possibility of cloning a d-dimensional quantum system without an ancilla is explored, extending on the economical phase-covariant cloning machine found in [Phys. Rev. A {\bf 60…
Multipartite Asymmetric Quantum Cloning
S. Iblisdir, A. Acin, N. Gisin +3
We investigate the optimal distribution of quantum information over multipartite systems in asymmetric settings. We introduce cloning transformations that take identical replic…
Experimental demonstration of quantum memory for light
Brian Julsgaard, Jacob Sherson, J. Ignacio Cirac +2
The information carrier of today's communications, a weak pulse of light, is an intrinsically quantum object. As a consequence, complete information about the pulse cannot, even in…
Loophole-free test of quantum non-locality using high-efficiency homodyne detectors
R. Garcia-Patron, J. Fiurasek, N. J. Cerf
We provide a detailed analysis of the recently proposed setup for a loophole-free test of Bell inequality using conditionally generated non-Gaussian states of light and balanced ho…
Quantum cloning at the light-atoms interface: copying a coherent light state into two atomic quantum memories
Jaromir Fiurasek, Nicolas J. Cerf, Eugene S. Polzik
A scheme for the optimal Gaussian cloning of coherent light states at the light-atoms interface is proposed. The distinct feature of this proposal is that the clones are stored in…
Pulsed squeezed vacuum characterization without homodyning
J. Wenger, J. Fiurasek, R. Tualle-Brouri +2
Direct photon detection is experimentally implemented to measure the squeezing and purity of a single-mode squeezed vacuum state without an interferometric homodyne detection. Foll…
