Homodyne characterization of continuous variable bipartite states / A. Porzio, V. D'Auria, S. Solimeno, S. Olivares, M. G. A. Paris. - In: INTERNATIONAL JOURNAL OF QUANTUM INFORMATION. - ISSN 0219-7499. - 5:1-2(2007), pp. 63-68.
Abstract:
We suggest a scheme to reconstruct the covariance matrix of continuous variable twomode states using a single homodyne detector and a few polarization elements. Our method can be used to fully characterize the bipartite Gaussian entangled states obtained at the output of a (nondegenerate) optical parametric amplifier driven below threshold, as well as to extract relevant informations on generic bipartite states made of two frequency degenerate but orthogonally polarized modes.
