Characterizing heralded single photons from a Bragg-reflection waveguide loss‐tolerantly via moment generating function
12:30 - 12:50
Kaisa Laiho, Marco Schmidt, Holger Suchomel, Martin Kamp, Sven Höfling, Christian Schneider, Joern Beyer, Gregor Weihs and Stephan Reitzenstein We measure the joint photon statistics of parametric down-conversion from a Bragg-reflection waveguide with transition-edge sensors, being true photon-number resolving detectors. Further, we utilize the normalized factorial moments of photon-number, which can be measured independent of losses, and the loss-corrected mean photon-number of the target state for reconstructing the photon-number parity of heralded single photons loss-tolerantly via the moment generating function. We take into account imperfections in the heralded state preparation and manipulation as well as investigate the boundaries of the method used for the state reconstruction.
