Tripartite quantum correlations obtained by post-selection from twin beams
Pavel Pavlicek, Jan Perina, Vaclav Michalek +2
Spatially-resolved photon counting of a twin beam performed by an iCCD camera allows for versatile tailoring the properties of the beams formed by parts of the original twin beam.…
Calibration of single-photon cameras using radioluminescent light sources
Radek Machulka, Václav Michálek, OndÅej 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…
Experimental photon addition and subtraction in multi-mode and entangled optical fields
Kishore Thapliyal, Jan PeÅina, OndÅej Haderka +2
Multiple photon addition and subtraction applied to multi-mode thermal and sub-Poissonian fields as well as twin beams is mutually compared using one experimental setup. Twin beams…
Revealing Nonclassicality of Multiphoton Optical Beams via Artificial Neural Networks
Radek Machulka, Jan PeÅina, Václav Michálek +2
The identification of nonclassical features of multiphoton quantum states represents a task of the utmost importance in the development of many quantum photonic technologies. Under…
