    time-frequency encodings have the potential to significantly advance quantum information
    science; however, practical applications require precise knowledge of the encoded
    quantum states, which becomes increasingly challenging for larger Hilbert spaces.
    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>"
