Tomography of Single-Photon Subtraction Process in Multiple Time-Frequency Modes
Young-Sik Ra, Clément Jacquard, Adrien Dufour, Claude Fabre, Nicolas Treps · Conference on Lasers and Electro-Optics · 2016
We present a method to characterize single-photon subtraction process in multiple time-frequency modes. To obtain complete information of the process, we use coherent-state quantum process tomography, and express the results by a quantum process matrix.
