Quantum Light State Engineering and Entanglement Generation by Multimode Photon Addition
Marco Bellini, Nicola Biagi, Luca Salvatore Costanzo, Alessandro Zavatta · 2018
One can entangle distinct field modes by the delocalized addition of a single photon. We present recent experiments on the characterization of entanglement created by adding single photons between modes initially containing light states of different sorts and sizes.
