Experimental detection of nonclassicality of single-mode fields via intensity moments
Ievgen I. Arkhipov, Jan Peřina, Ondřej Haderka +1
Nonclassicality criteria based on intensity moments and derived from the usual matrix approach are compared to those provided by the majorization theory. The majorization theory is…
Entanglement and nonclassicality in four-mode Gaussian states generated via parametric down-conversion and frequency up-conversion
Ievgen I. Arkhipov, Jan Peřina, Ondřej Haderka +2
Multipartite entanglement and nonclassicality of four-mode Gaussian states generated in two simultaneous nonlinear processes involving parametric down-conversion and frequency up-c…
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…
Nonclassicality Invariant of General Two-Mode Gaussian States
Ievgen I. Arkhipov, Jan Peřina, Jiří Svozilík +1
We introduce a new quantity for describing nonclassicality of an arbitrary optical two-mode Gaussian state which remains invariant under any global photon-number preserving unitary…
