Retrieving the Covariance Matrix of an Unknown Two-Mode Gaussian State by Means of a Reference Twin Beam
Ievgen I. Arkhipov, Jan Peřina
A method for revealing the covariance matrix of an unknown two-mode Gaussian state is given based on the interference with a reference twin beam whose covariance matrix is known. I…
Interplay of nonclassicality and entanglement of two-mode Gaussian fields generated in optical parametric processes
Ievgen I. Arkhipov, Jan Peřina, Adam Miranowicz
The behavior of general nonclassical two-mode Gaussian states at a beam splitter is investigated. Single-mode nonclassicality as well as two-mode entanglement of both input and out…
High spatial entanglement via chirped quasi-phase-matched optical parametric down-conversion
Jiří Svozilík, Jan Peřina, Juan P. Torres
By making use of the spatial shape of paired photons, parametric down-conversion allows the generation of two-photon entanglement in a multidimensional Hilbert space. How much enta…
Spatial and spectral properties of the pulsed second-harmonic generation in a PP-KTP waveguide
Radek Machulka, Jiří Svozilík, Jan Soubusta +2
Spatial and spectral properties of the pulsed second harmonic generation in a periodically-poled KTP waveguide exploiting simultaneously the first, second, and third harmonics of p…
