Photon subtraction from a multimode squeezed vacuum state
Adrien Dufour, Clément Jacquard, Young-Sik Ra, Claude Fabre, Nicolas Treps · 2017
We present the generation and characterization of a multimode non-gaussian state. We prepare squeezed vacua in multiple time-frequency modes, subtract a single photon, and then characterize the state by using mode-selective homodyne detection.
