This device can facilitate practical realizations of quantum information applications such as high-dimensional quantum key distribution and thus enables secure communication with enhanced information capacity. We characterize the mode-sorter through a detector tomography in 3 and 5 dimensions and find a fidelity up to 0.958 ± 0.030 at the single-photon level.</jats:p>"}],"language":[{"iso":"eng"}],"status":"public","author":[{"id":"88242","first_name":"Laura Maria","full_name":"Serino, Laura Maria","last_name":"Serino"},{"full_name":"Eigner, Christof","orcid":"https://orcid.org/0000-0002-5693-3083","last_name":"Eigner","id":"13244","first_name":"Christof"},{"id":"27150","first_name":"Benjamin","orcid":"0000-0003-4140-0556 ","full_name":"Brecht, Benjamin","last_name":"Brecht"},{"first_name":"Christine","id":"26263","last_name":"Silberhorn","full_name":"Silberhorn, Christine"}],"department":[{"_id":"15"},{"_id":"623"}],"user_id":"27150","publication":"Optics Express","publisher":"Optica Publishing Group","issue":"3","article_number":"5577","year":"2024","citation":{"chicago":"Serino, Laura Maria, Christof Eigner, Benjamin Brecht, and Christine Silberhorn. “Programmable Time-Frequency Mode-Sorting of Single Photons with a Multi-Output Quantum Pulse Gate.” <i>Optics Express</i> 33, no. 3 (2024). <a href=\"https://doi.org/10.1364/oe.544206\">https://doi.org/10.1364/oe.544206</a>.","apa":"Serino, L.
