Experimental investigation of the role of spatial correlations in optical integration with heralded single photons
L. Marques Fagundes Silva, R. C. Souza Pimenta, M. H. Magiotto +4
In this work, we demonstrate optical integration using heralded single photons and explore the influence of spatial correlations between photons on this process. Specifically, we e…
