Frontiers in OpticsMeasuring high-dimensional unitary transformations with undetected photonsSalini Rajeev, Mayukh LahiriPublished Jan 1, 2025• 0 citationsPublisherAbstractWe present a novel, quantum interferometric method of measuring high-dimensional unitary transformations. In contrast to existing methods, the proposed method does not require detecting the qudit on which the unitary transformation is performed.DOI10.1364/fio.2025.fth1c.2
