Characterization of bipartite states using a single homodyne detector
Virginia D'Auria, Alberto Porzio, Salvatore Solimeno +2
We suggest a scheme to reconstruct the covariance matrix of a two-mode state using a single homodyne detector plus a polarizing beam splitter and a polarization rotator. It can be…
Effect of noise and enhancement of nonlocality in on/off photodetection
Carmen Invernizzi, Stefano Olivares, Matteo G. A. Paris +1
Nonlocality of two-mode states of light is addressed by means of CHSH inequality based on displaced on/off photodetection. Effects due to non-unit quantum efficiency and nonzero da…
Squeezed Fock state by inconclusive photon subtraction
Stefano Olivares, Matteo G. A. Paris
We analyze in details the properties of the conditional state recently obtained by J. Wenger, et al. [Phys. Rev. Lett. {\bf 92}, 153601 (2004)] by means of inconclusive photon subt…
Gaussian states in continuous variable quantum information
Alessandro Ferraro, Stefano Olivares, Matteo G. A. Paris
These notes originated out of a set of lectures in Quantum Optics and Quantum Information given by one of us (MGAP) at the University of Napoli and the University of Milano. A quit…
Photon subtracted states and enhancement of nonlocality in the presence of noise
Stefano Olivares, Matteo G. A. Paris
We address nonlocality of continuous variable systems in the presence of dissipation and noise. Three nonlocality tests have been considered, based on the measurement of displaced-…
