Experimental estimation of entanglement at the quantum limit
Giorgio Brida, Ivo Degiovanni, Angela Florio +5
Entanglement is the central resource of quantum information processing and the precise characterization of entangled states is a crucial issue for the development of quantum techno…
Characterization of Spectral Entanglement of Spontaneous Parametric-Down Conversion Biphotons
G. Brida, V. Caricato, M. Genovese +3
We verified operational approach based on direct measurement of entanglement degree for bipartite systems. In particular spectral distributions of single counts and coincidence for…
Cosmology and entanglement
Marco Genovese
In this paper we present the problem of quantum to classical transition of quantum fluctuations during inflation and in particular the question of evolution of entanglement. After…
Chirped Biphotons and Their Compression in Optical Fibres
M. V. Chekhova, G. Kh. Kitaeva, O. A. Shumilkina +3
We show that broadband biphoton wavepackets produced via Spontaneous Parametric Down-Conversion (SPDC) in crystals with linearly aperiodic poling can be easily compressed in time u…
State reconstruction by on/off measurements
A. Allevi, A. Andreoni, M. Bondani +7
We demonstrate a state reconstruction technique which provides either the Wigner function or the density matrix of a field mode and requires only avalanche photodetectors, without…
