Conditional probabilities behind a beam splitter for an amplified single photon
A. Lukš, Vlasta Peřinová · Proceedings of SPIE, the International Society for Optical Engineering/Proceedings of SPIE · 1999
We calculate a joint distribution of the photon number and the momentum-like quadrature measured in a simple experimental scheme. We assume that any quantum state is preamplifier to compensate for the attenuation on a beam splitter. Particularly, we investigate a single input photon. We compare the measured joint distribution with quasidistributions related to partially symmetric orderings of the photon number and momentum-like quadrature operators.
