Nonclassicality of bright Greenberger-Horne-Zeilinger–like radiation of an optical parametric source
Konrad Schlichtholz, Bianka Wołoncewicz, Marek Żukowski · Physical Review A · 2021
The authors study the generation of nonclassical light using an optical parametric source by developing a detailed higher-order theory for the bright emissions of triples of Greenberger-Horne-Zeilinger photons. The results could potentially be useful for estimating the influence of the higher-order emissions on certain quantum informational protocols.
