Comment on "Entangled-Photon Imaging of a Pure Phase Object"
M. Bache, A. Gatti, E. Brambilla +3
Comment on A.F. Abouraddy, P.R. Stone, A.V. Sergienko, B.E.A. Saleh, and M.C. Teich, ``Entangled-Photon Imaging of a Pure Phase Object,'' Phys. Rev. Lett. 93, 213903 (2004). Unpubl…
Ghost imaging, quantum and classical aspects
A. Gatti, E. Brambilla, M. Bache +1
We analytically show that it is possible to perform coherent imaging by using the classical correlation of two beams obtained by splitting incoherent thermal radiation. A formal an…
Ghost imaging using homodyne detection
M. Bache, E. Brambilla, A. Gatti +1
We present a theoretical study of ghost imaging based on correlated beams arising from parametric down-conversion, and which uses balanced homodyne detection to measure both the si…
A " quantum public key " based cryptographic scheme for continuous variables
Patrick Navez, Alessandra Gatti, Luigi A. Lugiato
By analogy to classical cryptography, we develop a "quantum public key" based cryptographic scheme in which the two public and private keys consist in each of two entangled beams o…
Spatial entanglement of twin quantum images
Enrico Brambilla, Alessandra Gatti, Patrick Navez +1
We show that spatial entanglement of two twin images obtained by parametric down-conversion is complete, i.e. concerns both amplitude and phase. This is realised through a homodyne…
Quantum Holographic Teleportation of Light Fields
I. V. Sokolov, M. I. Kolobov, A. Gatti +1
We describe a continious variable teleportation scheme that allows to teleport the quantum state of distributed in space-time multimode electromagnetic field. Our teleportation pro…
