Analyzing quantum-light sources via a photon-number-resolving transition edge sensor — •Martin von Helversen1, Alexander Thoma1, Marco Schmidt1,2, Manuel Gschrey1, Peter Schnauber1, Jan-Hindrik Schulze1, André Strittmatter1, Jörn Beyer2, Sven Rodt1, Tobias Heindel1, and Stephan Reitzenstein1 — 1Institut für Festkörperphysik, Technische Universität Berlin, 10623 Berlin, Germany — 2Physikalisch-Technische Bundesanstalt, Abbestraße 1, 10587 Berlin, Germany
Solid-state quantum-light sources based on single semiconductor quantum dots (QDs) are promising candidates for a variety of applications in the research fields of quantum communication and quantum metrology. In order to better understand and directly access the photon statistics emitted by such sources, we employ a state of the art photon-number-resolving detection system consisting of a transition edge sensor (TES). Using the TES-detectors, we investigate two different types of sources, namely a single-photon source [1] and a twin-photon source [2], both based on deterministic QD devices. The obtained results enable us to reconstruct the photon number distribution emitted by the respective quantum emitter.
