Quantum Correlations in Three-Beam Symmetric Gaussian States Accessed via Photon-Number-Resolving Detection and Quantum Universal Invariants

Jan Peřina, Nazarii Sudak, Artur Barasiński +1

Quantum correlations of 3-beam symmetric Gaussian states are analyzed using their quantum universal invariants. These invariants, 1-, 2-, and 3-beam purities, are expressed in term…

Calibration of single-photon cameras using radioluminescent light sources

Radek Machulka, Václav Michálek, Ondřej Haderka +1

In this paper, we address the calibration of the quantum efficiency of single-photon cameras using radioluminescent light sources. The proposed methods are subsequently compared wi…

Quantumness and its hierarchies in PT-symmetric down-conversion models

Jan Peřina, Karol Bartkiewicz, Grzegorz Chimczak +4

We investigate the hierarchy of quantum correlations in a quadratic bosonic parity-time-symmetric system (PTSS) featuring distinct dissipation and amplification channels. The hiera…

Efficient Characterization of N-Beam Gaussian Fields Through Photon-Number Measurements: Quantum Universal Invariants

Nazarii Sudak, Artur Barasiński, Jan Peřina +1

Quantum universal invariants of general N-beam Gaussian fields are investigated from the point of view of fields' intensity moments. A method that uniquely links these invariants,…
