Experimental characterization of photon-number noise in Rarity-Tapster-Loudon-type interferometers
In this paper, we develop a simple model describing inherent photon-number noise in Rarity-Tapster-Loudon-type interferometers. This noise is caused by generating photon pairs in the process of spontaneous parametric down-conversion and adding a third photon by attenuating the fundamental laser mode to the single-photon level. We experimentally verify our model …
