Compressive characterization of biphoton frequency spectra
Abstract
Frequency-bin qudits constitute a promising tool for quantum information processing. Here we use compressive sensing to characterize the spectral correlations of entangled photon pairs in a quantum frequency comb, obtaining a 26-fold reduction in measurement time compared to raster scanning.
