Self-guided tomography (SGT) has emerged as a practical and scalable technique for this purpose in the spatial domain. Here, we apply SGT to estimate time-frequency states using a multi-output quantum pulse gate. We achieve fidelities of more than 99% for 3- and 5-dimensional states without the need for calibration or post-processing. We demonstrate the robustness of SGT against statistical and environmental noise, highlighting its efficacy in the photon-starved regime typical of quantum information applications.</jats:p>"}],"issue":"2","publication":"Quantum Science and Technology","type":"journal_article","department":[{"_id":"15"},{"_id":"623"}],"date_created":"2025-12-18T16:07:11Z","status":"public","user_id":"27150","volume":10,"_id":"63215","publisher":"IOP Publishing","citation":{"mla":"Serino, Laura Maria, et al. “Self-Guided Tomography of Time-Frequency Qudits.” <i>Quantum Science and Technology</i>, vol. 10, no. 2, 025024, IOP Publishing, 2025, doi:<a href=\"https://doi.org/10.1088/2058-9565/adb0ea\">10.1088/2058-9565/adb0ea</a>.","ama":"Serino LM, Rambach M, Brecht B, Romero J, Silberhorn C.
