Characterizing a high-dimensional unitary transformation without measuring the qudit it transforms
Salini Rajeev, Mayukh Lahiri
We present a method for reconstructing an arbitrary high-dimensional unitary transformation without detecting the qudit that it transforms. We demonstrate the method using orbital…

Complete Measurement of Two-Photon Density Matrix by Single-Photon Detection
Salini Rajeev, Mayukh Lahiri
The reconstruction of density matrices from measurement data (quantum state tomography) is the most comprehensive method for assessing the accuracy and performance of quantum devic…
