Gouy phase in nonclassical paths in a triple-slit interference experiment

摘要

We propose a simple model to study the Gouy phase effect in the triple-slit experiment in which we consider a nonclassical path. The Gouy phase differs for classical and nonclassical paths as it depends on the propagation time. In this case the Gouy phase difference changes the Sorkin parameter kappa used to estimate the nonclassical path contribution in a nontrivial way, shedding some light on the implementation of experiments to detect nonclassical path contributions.
