Macroscopic entangled states by delocalized single-photon addition
Nicola Biagi, Luca S. Costanzo, Marco Bellini, Alessandro Zavatta · 2019
We report an experimental realization of macroscopic entangled states obtained by applying delocalized single-photon creation operations on two uncorrelated temporal modes populated by coherent states. Entanglement is preserved as the mean photon number increases.
