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,…
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…
