Distillation of the two-mode squeezed state    [PDF]

Yuri Kurochkin, Adarsh S. Prasad, A. I. Lvovsky

We experimentally demonstrate entanglement distillation of the two mode squeezed state. Applying the annihilation operator to both modes, we increase the fraction of the two-photon component in the state, resulting in the increase of both squeezing and entanglement by about 50%.
