Compressive Sensing of Photonic Qudits through Positivity Constraints. (QTu8A.5)

Presenter: Jaroslav Rehacek, Palacky University

We present a compressed-sensing inspired method to ascertain any rank-deficient qudit state, which we experimentally encode in photonic orbital angular momentum. Our technique provides an easy and accurate way to identify quantum sources and systems.
